RISDetermination of Stabilizing Forces Acting on Piles to Reinforce Slurry Trench against Globe Collapse
Publisher: ASCE
Abstract: Concrete piles are used conventionally to reinforce slurry trench against global collapse during excavation in surrounding soft soil layers. In this paper, the stabilizing forces acting on piles were analyzed with the ...
Improved Vacuum Preloading Method Combined with Sand Sandwich Structure for Consolidation of Dredged Clay-Slurry Fill and Original Marine Soft Clay
Publisher: ASCE
Abstract: An improved vacuum preloading method combined with a sand sandwich structure (SSS) was developed to facilitate the consolidation of dredged clay-slurry fill and original soft marine clay for land reclamation. In this method, ...
Analytical Solution for Nonlinear Consolidation Considering Time-Dependent Well Resistance and Lateral Deformation under Vacuum Preloading
Publisher: ASCE
Abstract: The consolidation behavior of a foundation with vertical drains under vacuum preloading is affected by the lateral deformation and well resistance. In this study, a nonlinear consolidation model is developed based on the ...
Analytical Solution for Radial Displacement–Dependent Earth Pressure Acting on Underwater Rock-Socketed Circular Diaphragm Walls
Publisher: ASCE
Abstract: The distribution of lateral earth pressure acting on underwater rock-socketed circular diaphragm walls was investigated using theoretical analyses. Emphasis was placed on the relationship between the motion modes associated ...
Enzyme-Induced Carbonate Precipitation Using Yellow Soybean for Eco-Friendly Treatment of Expansive Soils
Publisher: ASCE
Abstract: We conducted an experimental study on the swelling–shrinking characteristic of expansive soil treated with enzyme-induced carbonate precipitation (EICP) using yellow soybean. A series of tests including the free swell test, ...
Factors Affecting Improvement of Engineering Properties of MICP-Treated Soil Catalyzed by Bacteria and Urease
Publisher: American Society of Civil Engineers
Abstract: Microbial induced calcite precipitation (MICP) is one of the potential methods for improvement of engineering properties of soil. A laboratory study was conducted to investigate the influence of various factors on engineering ...
