摘要
根据砂土的室内剪切试验-全模试验和半模试验,分析了影响砂土抗剪强度的主要因素。指出了均匀砂和不同级配的砂对砂土抗剪强度的影响。从室内试验可以看出,均匀砂中,砂样的抗剪强度随着法向应力的增大而增大,而且抗剪强度增长幅度与法向压力基本成正比增长的趋势。相同法向压力下,砂土的抗剪强度随着粒径的增大而增大,内摩擦角也随之变大。可以很好的说明,砂土的抗剪强度与颗粒大小有关。
Based on the full model and half model shearing test on sand, this factor on the shear strength of the sand. Form the shearing test, it is concluded that the uniform sand increased with the pressure around the sample＇s increase by direct grading sand, the shear strength increases with the diameter of the sand.
