摘要
本文分析偏轴压力 ,复杂性的应力条件以及有效的剪切面积对参数的影响 ,得出 C,Φ的偏差趋势 ,指出直剪试验参数误差过大 ,建议尽量采用三轴仪进行强度试验。
In this paper analysed is the effect of deviated axial pressure, complicated state of stress and effective area of cross section on parameters. The trend of error of C and Φ is found out, and the error of parameters in direct shear test is pointed out. It is suggested that triaxial apparatus be used in strength tests.
