The Failure Of Oil Storage Tanks And Their Control, Stanislav Dovnarovitch, Yurji Ivanov Jun 1988

The Failure Of Oil Storage Tanks And Their Control, Stanislav Dovnarovitch, Yurji Ivanov

International Conference on Case Histories in Geotechnical Engineering

The paper discusses of some results of flexible footings and their models behaviour in the case of loading-unloading cycles applied to them. The revealed effects have been used to explain the causes of some tanks failures. It has been shown that one of the possible causes is the difference between the displacements of the tank bottom and soil under it following unloading and subsequent loading. A simple technique has been proposed to prevent the failures that can be easily applied when constructing the tanks. The application of the technique both eliminates the causes of the failures and greatly reduces the …

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 …

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.

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 …

Verification And Evaluation Of The Result Of Liquefiable Soil Treated With Vibroflotation, Bao-He Gu, Zong-Han Hu, Wan-Yu Wang

International Conference on Case Histories in Geotechnical Engineering

Result of liquefiable soil treated with vibroflotation is recommended in this paper through the treatment of soil of a large power plant. The site lies in macroseismic area, where the bearing capacity of soil in layer B was low and there existed liquefaction potential. Verifications before and after treatment depicted clearly that the result of vibroflotation was excellent. Not only the liquefaction trend of soil was eliminated but also the bearing capacity was enhanced. Various testing methods were introduced and evaluation of liquefaction potential of soft saturated soil before and after treatment were analyzed and discussed in this paper.

India's First Venture Relating To Subsurface Drainage By Horizontal Drains, T. K. Natarajan, A. V. S. R. Murty, Deep Chandra

International Conference on Case Histories in Geotechnical Engineering

Landslides in the Nilgiris district in 1978-79 1 caused heavy damages to property and human life. The field studies indicated that in certain spots, the build up of excess hydrostatic pressure, caused by direct and indirect ingress of water into the soil mantle, is the main cause for certain landslides in the region. The paper attempts to give the total case history relating to a pioneering venture of its kind towards the correction of landslides undertaken in India. The case history assumes special significance in as much as the horizontal drains successfully installed for the first time in this country, …
