碎石桩加固饱和粉土地基的抗液化特性
Characteristics of Liquefaction Resistance for Stone Columns Treated in Saturated Silt Ground
摘要
Abstract
Liquefaction of saturated silt is still an important topic remaining in geotechnical earthquake engineering besides liquefaction of sands. The risk of liquefaction and associated ground deformation can be reduced by various ground-improvement methods including the stone column technique. The effectiveness of stone columns for the prevention of soil liquefaction during an earthquake is often threefold: densification, drainage and the reduction of the total cyclic shear stress in the soil. However, there are obvious difference of characteristics of stone columns liquefaction resistance between in saturated silts and in sands.In this paper, a detailed review on effectiveness of densification, drainage and reinforcement of stone columns for the resistance of soil liquefaction during earthquakes is presented. The suggestions are offered for some problems worthy of further study.关键词
