Ground Movement Characteristics Above Mined Panels In Appalachia-An Empirical Approach, M. Karmis, T. Triplett, P. Schillizzi, G. Hasenfus
Ground Movement Characteristics Above Mined Panels In Appalachia-An Empirical Approach, M. Karmis, T. Triplett, P. Schillizzi, G. Hasenfus
International Conference on Case Histories in Geotechnical Engineering
The growing recognition of mining subsidence and its effects has provoked numerous investigations into the modeling and prediction of this phenomenon. Through an analysis of case histories and examination of the various modeling techniques, it has become apparent that empirical studies currently represent the most realistic approach to this problem. However, the collection, analysis and interpretation of subsidence and strain data acquired from case studies presents substantial difficulties, due to varying monitoring techniques and methods of analysis. In this paper it is suggested that a prescribed monitoring program could eliminate these problems and ensure quality data by standardizing the measurement …

Improvement Of A Dumped Rockfill Foundation By Dynamic Consolidation, Adrian Wightman, Nelson F. Beaton
Improvement Of A Dumped Rockfill Foundation By Dynamic Consolidation, Adrian Wightman, Nelson F. Beaton
International Conference on Case Histories in Geotechnical Engineering
The paper describes an Industrial Park development, on the British Columbia coast, where Dynamic Consolidation was chosen to densify a loose rockfill prior to construction of a modern high capacity sawmill on shallow foundations. The design and execution of the compaction are described. The in situ tests used to monitor the compaction are described and results presented. It is concluded that the desired result was achieved, and this is supported by a survey of foundation elevations taken four years after construction.
Instrumentation Of A Sewer Tunnel In Weak Singapore Soils, K. W. Lo, G. P. Karunaratne, S. L. Lee
Instrumentation Of A Sewer Tunnel In Weak Singapore Soils, K. W. Lo, G. P. Karunaratne, S. L. Lee
International Conference on Case Histories in Geotechnical Engineering
The effects of tunnelling in soft ground consisting mainly of Singapore marine clay were recently monitored to establish ground response characteristics. A sewer tunnel of 2.1 m square section was driven at a depth of 6.3 m in this soil by jacking conventional shield and face supports against installed timber lining. Ground response was monitored by an assortment of field instruments read over several weeks' duration. Peck's proposal (1969) of fitting a normal distribution profile to lateral surface settlement field plots when a heading is well past, and the suggestion by Oshikoshi et al 0978) that similar profiles may be …
Mechanism Of Dynamic Consolidation And Its Environmental Effect, Zhong-Qi Wang, Xiang-Iin Deng
Mechanism Of Dynamic Consolidation And Its Environmental Effect, Zhong-Qi Wang, Xiang-Iin Deng
International Conference on Case Histories in Geotechnical Engineering
This paper is contributed as case histories in ground soil improvement with particular emphasis of dynamic consolidation. The authors try to present as much as they got from the field testings and observations including vibrational parameters, pore pressures, stereoscopic photogrammetry, etc. in order to trace the real behaviour of ground movement during tamping. It is believed that all the data got from the field work are rather informative and illustrative than that from theoretical modelling in the laboratory. Thus, some highlights relating effective thickness of compaction, maximum spacing between compaction points, number of blows for optimum tamping and seismic attenuation …
Performance Of Sand Drains In A Tidal Marsh, R. P. Long, W. H. Hover
Performance Of Sand Drains In A Tidal Marsh, R. P. Long, W. H. Hover
International Conference on Case Histories in Geotechnical Engineering
This paper presents the field behavior of a jetted sand drain installation at a preloaded wastewater treatment facility site in Gloucester, Massachusetts, U.S.A. The site is underlain by surficial estuary deposits above a stratum of stiff to soft clays. Detailed subsurface explorations and laboratory testing program provided data to predict amounts and rates of primary compression and rates of secondary compression in the referenced strata. The field behavior is compared to predictions through analyzed values of total settlement at the end of primary compression, coefficient of consolidation, and coefficient of secondary compression. A field instrumentation program allowed monitoring of settlements …
Preloading For Large Storage Building, A. C. Stamatopoulos, P. C. Kotzias
Preloading For Large Storage Building, A. C. Stamatopoulos, P. C. Kotzias
International Conference on Case Histories in Geotechnical Engineering
The properties and method of preloading a 11 m erratic deposit of soft clays and loose sands, are described. Under the preload embankment of 12 m the deposit compressed an average of 7%. Settlement developed rapidly and excess porepressure dissipated within few days, never exceeding 2.1 m of water head. After preload removal borings were performed to compare results with those obtained on the untreated site. This comparison showed that the compressibility and strength of both the clayey and sandy components improved substantially and that the subsurface became more homogeneous. The projected structure built on the improved ground has performed …
Settlements Induced By Soft Ground Tunneling, Miguel P. Romo
Settlements Induced By Soft Ground Tunneling, Miguel P. Romo
International Conference on Case Histories in Geotechnical Engineering
Ground settlements induced by air-pressure shield tunneling throughout the soft clays of Mexico City have been monitored in five test sections by means of settlement points installed at various depths and distances from the tunnel axis. Subsoil conditions and soil characteristics at each site were thoroughly studied in the field and in the laboratory. Measured settlement profiles have been compared to those computed by a simplified analytical procedure showing very good agreement.

Soil-cement backfills have been analyzed, designed and tested for the Alto Lazio Nuclear Power Plant in Italy. Extensive analyses were performed to evaluate the stability of and stresses in soil-cement foundation backfills. Soil-structure interaction was also analyzed. The minimum required cement content for foundation and general backfills was established and verified by means of laboratory and field tests. Foundation backfills were designed for two major buildings of the plant.
Subsidence Affects Due To Gypsum Solution In Syracuse, New York, G. W. Lee, S. P. Clemence, S. K. Bhatia, S. Anagnost
Subsidence Affects Due To Gypsum Solution In Syracuse, New York, G. W. Lee, S. P. Clemence, S. K. Bhatia, S. Anagnost
International Conference on Case Histories in Geotechnical Engineering
Two apartment buildings owned by Syracuse University in the Slocum Heights area underwent extensive differential settlement manifested by foundation cracks. Examination of rock exposures in the nearby area revealed the presence of gypsum beds. Onsite boring and investigation revealed that regrading and installation of french drains and storm sewers influenced the groundwater regime resulting in solutioning of the gypsum and subsequent collapse of underground cavities. Remedial measures included alteration of drainage system and underpinning of apartment structures.
