Settlement Predictions In Residual Soils By Dilatometer, Pressuremeter And One-Dimensional Compression Tests: Comparison With Measured Field Response, Roy H. Borden, William J. Sullivan, Weichen Lien Jun 1988

Settlement Predictions In Residual Soils By Dilatometer, Pressuremeter And One-Dimensional Compression Tests: Comparison With Measured Field Response, Roy H. Borden, William J. Sullivan, Weichen Lien

International Conference on Case Histories in Geotechnical Engineering

A case study investigating settlement predictions based on data from one dimensional compression, pressuremeter (PMT) and dilatometer (DMT) tests is presented. A relationship is established between PMT and DMT evaluated moduli and the standard penetration N values. These relationships are utilized in the settlement computations. The predictions obtained by each method are compared to the actual measured settlement. The column location at which settlement observations were made was instrumented with strain gages to measure the actual applied loads. A comparison between actual and design loads is made. Settlement predictions using PMT were performed utilizing two different existing approaches. A distinction …

Accelerated Consolidation Of Soft Clays Using Wick Drains, J. R. Davie, M. R. Lewis, L. W. Young Jr. Jun 1988

Accelerated Consolidation Of Soft Clays Using Wick Drains, J. R. Davie, M. R. Lewis, L. W. Young Jr.

International Conference on Case Histories in Geotechnical Engineering

Construction of the New Istana for the Sultan of Brunei required that fill slopes up to 85 feet high be placed on very soft compressible floodplain soils. Wick drains installed in the soft sediments accelerated their consolidation and reduced long-term settlements. The consolidation also produced a strength increase in the soft soils that allowed the fill to be constructed without danger of a major base slip failure. Instrumentation installed in the floodplain soils provided data on excess porepressures built up during the fill placement, and on the resulting settlements. The measured porepressures and settlements were in good agreement with the …


Advances In The Construction And Design Of Jet Grouting Methods In South America, Giorgio Guatteri, Joseph L. Kauschinger, Antonio C. Doria, Edward B. Perry Jun 1988

Advances In The Construction And Design Of Jet Grouting Methods In South America, Giorgio Guatteri, Joseph L. Kauschinger, Antonio C. Doria, Edward B. Perry

International Conference on Case Histories in Geotechnical Engineering

This paper presents a brief historical development of the two most popular jet grouting methods used in South America, namely, the chemical churning pile method (CCP) and jumbo jet grouting. Advantages and limitations of each procedure are cited. A brief discussion follows covering the history of CCP jet grouting in South America. Field trials performed to improve the design methodology and construction of CCP and jumbo jet grouted columns are presented. Finally, three case histories are presented to illustrate the use of jumbo jet grouting where limited head room exists, jet grouting in close proximity to pile supported structures, formation …


Designing Geotextile Support For Submarine Power Cables, K. Y. C. Chung Jun 1988

Designing Geotextile Support For Submarine Power Cables, K. Y. C. Chung

International Conference on Case Histories in Geotechnical Engineering

Six 36 cm diameter submarine pipe-cables were buried in a 1.2 km long, fabric-lined trench in the soft river mud under 17 m average water head across the Hudson River about 4.8 km north of the Newburgh Bridge, New York. This paper describes the design considerations based on geotechnical point of view of using geotextile to support submarine power cables.


Geogrid Reinforced Soil Retaining Wall On Compressible Soils, R. L. Curtis, V. E. Chouery-Curtis, D. A. Miller Jun 1988

Geogrid Reinforced Soil Retaining Wall On Compressible Soils, R. L. Curtis, V. E. Chouery-Curtis, D. A. Miller

International Conference on Case Histories in Geotechnical Engineering

A geogrid reinforced soil wall with a wrap-around facing system was successfully constructed on soft, compressible alluvial and residual soils. An originally designed 20-foot (6.1 m) high, reinforced concrete cantilever retaining wall was not constructed because of the expected settlements induced by the wall and backfill. The geogrid reinforced wall was utilized because of its ability to withstand the estimated settlement and because it was considered less expensive than providing deep foundation support of a cantilever wall. This paper discusses the design, construction, and performance of the geogrid reinforced wall.


Geotechnical Studies Of Foundation Of A Tilted Tank At Parikshatgarh, India, G. C. Nayak, B. Singh, P. K. Jain Jun 1988

Geotechnical Studies Of Foundation Of A Tilted Tank At Parikshatgarh, India, G. C. Nayak, B. Singh, P. K. Jain

International Conference on Case Histories in Geotechnical Engineering

An overhead tank of 200 KL capacity and 9 m staging was constructed in year 1975 at the ancient historical site at Parikshatgarh, Meerut, India. The depth of foundation is 1.6 m and inner and outer diameters of annular raft is 6.8 m and 10.3 respectively. In year 1978, the overhead tank was observed to be tilted. Detailed geotechnical studies have been conducted in 1987 to find out the causes of tilting of the tank and tilts have been measured every month for last one year. It is interesting to note that in spite of severe tilt of 4.3 cm/meter …


Impact Of Tunneling On Two Brick-Bearing-Wall Structures, Marco D. Boscardin Jun 1988

Impact Of Tunneling On Two Brick-Bearing-Wall Structures, Marco D. Boscardin

International Conference on Case Histories in Geotechnical Engineering

The responses or a pair or brick-bearing-wall structures to nearby construction or twin, shield driven 21-ft-diameter tunnels in soil are examined. Horizontal and vertical ground displacements are summarized and discussed, as well as, horizontal and vertical displacements, tilting, distortion, and damage sustained by the structures. Transient features or the developing settlement trough and effects on building response are also examined and discussed.


Long Term Building Performance Over An Injected Subgrade, Ronald F. Reed, Paul Wright Jun 1988

Long Term Building Performance Over An Injected Subgrade, Ronald F. Reed, Paul Wright

International Conference on Case Histories in Geotechnical Engineering

Several foundation designs and stabilization methods are used with varying degrees of success to cope with the problem of expansive clays. Many of these methods are very expensive, therefore alternate technology that is both cost and performance effective has been developed. This paper presents a case history with pre- and post- stabilization test data for a 4-building project where pressure injection of lime and water was used to preswell weathered clay-shale to a depth of 10 feet. Use of pressure injection technology economically reduced post construction movements to 0.5 inches to 1.8 inches over a 7 year monitoring period. Movements …


Recent Examples Of Cut And Fill Reinforcement On A41-Highway In France, Trân Vô Nhiêm Jun 1988

Recent Examples Of Cut And Fill Reinforcement On A41-Highway In France, Trân Vô Nhiêm

International Conference on Case Histories in Geotechnical Engineering

At EVIRES PASS, between ANNECY and MONT BLANC in FRANCE, subsoil is made up of unstable clayey natural versants and marly bedrock affected by previous or current slidings. The problems encountered during the new A41-Highway construction were aggravated by the proximity of Road and Railway located on top of the same versant. The final Design consisted of succession of cuts and embankments with special soil reinforcement techniques to improve stability. So two existing unstable Railway embankments were promptly consolidated by "soil nailing" with driven steel dowel-piles which were either anchored or not. Two other high cuts in marls and sandstones …
