ANALYSIS AND DESIGN OF EXCAVATION SUPPORT SYSTEM IN SOFT CLAY
… design procedures for deep excavations in soft clay in Singapore are not always adequate. Consequently, difficulties such as large strut loads and excessive ground movements are often encountered. Therefore, a method was proposed for the design of excavation support system in soft clay. The …

Experimental and numerical study of primary consolidation of soft clay
… are performed on two natural soils, Maine Blue clay (MBC) and San Francisco Bay mud (SBM). The numerical simulation programs focus on the simulation of the GCRS test to simulate the excess pore pressure distribution during the gradient-controlled loading phase and the oedometer tests. The strain …

Analysis of large deformation offshore geotechnical problems in soft clay
… investigates two large deformation problems in soft clay and proposes a methodology for performing coupled flow and deformation analyses with advanced effective stress models. The first part of the research focuses on realistic 3-D finite element analyses (using AbaqusTM Standard) of a conductor …

Rapid Soil Stabilization of Soft Clay Soils for Contingency Airfields
… rates of stabilizers to increase the strength of soft clay soils (initial CBR = 2) within 72 hours for contingency airfields to support C-17 and C-130 aircraft traffic. Pavement design charts for various aircraft loading conditions were generated using the Pavement-Transportation Computer Assisted …

Stabilization of Soft Clay Subgrades in Virginia Phase I Laboratory Study
… in Virginia consist of wet, highly plastic clay or other troublesome soils. Such soils can be treated with traditional lime and cement stabilization methods. Alternatives, including lignosulfonates and polymers, are available, but their performance record is mixed and solid engineering data …

Scale Model Shake Table Testing of Underground Structures in Soft Clay
… rectangular tunnel cross-section embedded within soft clay. San Francisco Young Bay Mud was used as a prototype soil for developing a scale model soil mixture consisting of kaolinite, bentonite, class C fly ash, and water. A single cell Bay Area Rapid Transit (BART) cut-and-cover subway tunnel was …

Ground source heat storage and thermo-physical response of soft clay
… fluctuations and possibly deformation of soft clays. This thesis evaluates the thermo-mechanical response of soft clays to seasonal heat storage and associated temperature fluctuations. A literature review reveals that, in normally consolidated to lightly overconsolidated clays, increases …

Asphalt binder and mixture performance using Batu Pahat soft clay as modifier
… method for each additive ratio. However, using soft clay as filler to modify asphalt binder and mixture was not intensively done by researchers. Additionally, physical properties results of penetration and softening point show that soft clay can increase the binder stiffness, while storage …

Finite element study of geosynthetic encased stone columns in sensitive soft clay
Some normally consolidated soft soils manifest strength sensitivity, ie these soil manifest strain softening when shear in an undrained mode. These soils, referred to as sensitive soft soils, have the typical features of strain hardening in drained shearing and strain softening in undrained …

Scale Model Shake Table Testing of Seismic Earth Pressures in Soft Clay
… the development of seismic earth pressures in soft clay. The soft clay was modeled after prototype San Francisco Bay Mud consisting of a mixture of kaolinite, bentonite, class C fly ash and water. A flexible walled testing container founded on a 1g shake table was used to house the model soil …

Scale Model Shake Table Testing of Shallow Embedded Foundations in Soft Clay
<p>This research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and foundation soil (known as soil-foundation-structural-interaction or SFSI). In previous research, SFSI effects have been quantified through …

Numerical and physical modelling of piled rafts on soft clay under combined loading
… key aspects of the behaviour of piled rafts in soft clay soil, namely overall capacity, load sharing between the piles and the raft, and failure mechanisms. The problem was tackled by both numerical and physical modelling and different configurations of the system were examined, including the …

Laboratory and Numerical Investigation for the Mobility of Ground Vehicles on Soft Clay
The mobility of ground vehicles on soft, fine-grained soils is hindered by low traction and reduced load-bearing capacity, posing significant challenges for heavy-duty vehicles, such as military transport and construction equipment. Enhancing vehicle stability on these terrains is essential for …

An experimental method for visualizing undrained shearing failure in a transparent soft clay surrogate
… of four laboratory shear-testing techniques in a soft clay surrogate, Laponite RD, at shallow depths with minimal boundary effects. The thesis developed a procedure for tracking deformation in Laponite RD as a soft clay surrogate for the miniature shear vane and the T-bar, ball, and cone …
