不同排水路径下饱和软黏土固结试验研究
Study on the consolidation test of saturated soft clay under different drainage paths
摘要
Abstract
In order to study the variation of displacement,pore pressure and consolidation coefficient of samples under different consolidation pressures and drainage paths.By using the GDS consolidation system,a series of consolidation tests are carried out under different drainage paths.The results indicated that with an increase in consolidation pressure,the final settlement of both horizontally and vertically drained consolidation specimens gradually increased.During radial drainage consolidation,the maxi-mum pore water pressure of the specimen was slightly smaller than that of vertically drained consolidation,and pore pressure dissipated more quickly.The coefficient of consolidation for vertically drained specimens slightly increased with an increase in consolidation pressure.The increase was more pronounced when the consolidation pressure is relatively low,and it becomes more gradual after the consolidation pressure exceeds a certain value.When drainage boundaries are well-established,the rate of soil consolidation is determined by the permeation speed of water in the soil,with minimal influence from drainage boundaries.关键词
