通过直剪与无侧限抗压强度试验，研究了含水率对麦秸秆加筋土抗剪强度指标与无侧限抗压强度的影响。研究结果表明：一定的含水量是麦秸秆发挥加筋性能的必要条件。随着含水率的增加，麦秸秆加筋土的粘聚力呈现先增大后减小的趋势，以最佳含水率时粘聚力最大；然而，加筋土的内摩擦角却随含水率的增加而逐渐减小。在合适的含水率条件下，麦秸秆加筋土的最佳质量加筋率在0．1％至0．3％间。

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%.
