含水率对麦秸秆加筋土强度影响的试验研究
Experiment on influence of water content on soil strength reinforced with wheat straw
摘要
Abstract
Through direct shear test and unconfined compressive strength test, the paper researched the influence of water content on the shear strength index and unconfined compressive strength of the soil re -inforced with wheat straw .The results show that certain water content is a necessary condition for the per-formance of soil reinforced with wheat straw. With the increase of water content, the cohesion of soil rein-forced wheat straw shows a trend from first increase to then decrease .When the moisture content reaches the optimum , the value of cohesion reaches the maximum .However , the internal friction angle of rein-forced soil gradually decreases with the increase of moisture content .Under the condition of certain water content, the optimal reinforcement rate of wheat straw fibers is between 0.1%to 0.3%.关键词
