在普通土大三轴仪上进行土的应力路径试验的探讨

The Study on Stress Pathes of Soil by Using General Large Scale Triaxial Apparatus

本文介绍了在普通士大三轴仪上对租粒土进行各种不同应力路径试验的方法,并推导出试验过程中轴向荷载的计算公式,为模拟不同土工建筑物的实际应力路径,建立土的本构关系打下了实验基础。

The experimental methods of stress path control for coarse grained soil in the conventional large scale triaxial tests are described. The calculative formula of axial loading during the test is deduced. This work provides a useful experimental foundation in simulating the practical stress pathes of geotechnical structures and in establishing the constitutive relations of materials.
