土的直接剪切试验与影响因素分析

Analysis on the Direct Shear Test of Soil and the Influencing Factors

抗剪强度指标C和φ是评价岩土体性质和工程设计的重要参数,在工程设计质量和工程施工中起着非常重要的作用。详细介绍了直接剪切试验的步骤和计算公式,并以图解的形式使得试验过程更加清晰明确,指出了影响直接剪切试验的因素与试验过程中应该注意的问题,为试验人员提供参考。

The Indicators of the shear strength,C and j,are the important parameters for the evaluation on the geotechnical property and engineering design,and play very important roles in engineering design quality and engineering construction.This paper introduces the steps and calculation formula of direct shear test,makes the test process more clear with the graphic mode,and points out the factors influencing the direct shear test and some matters needing attention in the test,providing some references for the testers.
