摘要: 钙质砂有着区别于石英砂的力学特性,抗剪强度是其中一个重要指标,也是为工程实践提供参考的关键数据。直接剪切试验是常用的一种测试钙质砂抗剪强度的室内试验方法。采用TKADSS4四联直剪仪,对相同干密度、不同含水率的钙质砂进行多组平行试验,探究含水率对其抗剪强度的影响规律。

Abstract: The mechanical properties of the calcareous sand are different from those of quartz sand or land origin. The shear strength is an important index that is widely used in the engineering practice. The direct shear test is a common laboratory strength test method for calcareous soils. The TKADSS4 type direct shear test equipment was used for the testing of calcareous sand samples with the same dry density and different moisture contents. The influence of moisture content on the shear strength was investigated.
