摘要
对Ｔｏｒｖａｎｃ剪切仪的工作机理作了系统的理论分析，并推导出有关参数的计算公式．指明了该仪器不足之处，研制出改进型的模型仪器．对Ｔｏｒｖａｎｃ剪切仪测定值的稳定性及其影响因素做了多方面的试验工作．利用测试成果，统计得出Ｔｏｒｖａｎｃ剪切强度值与三轴、直剪、无侧限压缩及袖珍贯入仪等试验所得相应不排水剪切强度值间的相关关系式，还探讨了用Ｔｏｒｖａｎｃ剪切仪确定液、塑限的可能性．提出了尚需研究的课题．
The mechanism of the Torvane shear device is analysed theoretically and the formulas arederived for calculating the parameters of shear strength.This research the points out some deficiencicsof the Torvane shear device in the current use and develops its newly improved model.Therepeatability of test results obtained by the Torvane shear device test is discussed and the factors ofinfluencing the test results are investignted. Through statistical analysis, the relative equations areachieved between the shear strengthes gained by Torvane shear device and the undrained shearstrengthes obtained by the triaxical shear test,direct shear test, unconfined compression test, andpocket penetration test respectively.The research tests tries to find out if the Torvane shear device testcan be used to determine the plastic limit and liquid limit. Finally some questions for further study anddiscussion are proposed.
