System reliability-based geotechnical design of braced excavations in soft clays
This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...
متن کاملEstimation of the compression behaviour of reconstituted clays
The void index is a relative quantity measuring the position of the current void ratio of a clay against the void ratios of the clay at two specific vertical effective stresses (i.e., σ v ′ = 100 kPa and σ v ′ =1000 kPa). Based on this concept, a simple systematic tool is proposed for estimating the compression behaviour of reconstituted clays over a wide range of stresses and water contents. F...
متن کاملCharacterization by Sampling and in Situ Testing – Connecticut Valley Varved Clay
Varved clays, which consist of alternating layers of silt and clay, are common in glaciated regions of North America and Northern Europe. This layering results in several unique engineering properties making varved clays a challenging soil for engineering design. Varved clays have hydraulic conductivity and undrained shear strength anisotropy that far exceeds that of most other soils. The stren...
متن کاملFactors Affecting Long-Term Efficiency of Compensation Grouting in Clays
Compensation grouting has been attracting attention in recent years to control ground settlement caused by underground construction. A successful and effective application of compensation grouting depends not only on the use of a good monitoring system in the field but also on a fundamental understanding of grout behavior in soils. For compensation grouting in clay, there is a need to consider ...
متن کاملPermeability Studies in Marine Clays Stabilized with Lime Column
Soft marine clays are very sensitive to changes in the stress system, moisture content and system chemistry of the pore fluid. Geotechnical engineers feel a necessity to improve the behavior of these deposits using anyone of the available ground improvement techniques. In the present investigation an attempt has been made to improve the permeability of a marine clay using the lime column techni...
