| 摘 要： | 原位水平推剪试验是一种常用的试验方法,但由于在对类似与土石混合体这类极度不均匀的岩土体进行试验时,其滑动面通常极为不规则。作者在三维极限平衡理论分析的基础上,推导出了野外大型原位水平推剪试验在考虑三维滑动面时的强度参数计算方法,并采用VC .NET编制了相应的数据处理系统(HPT-3D),为原位水平推剪试样提供了新的处理技术。将该法应用于虎跳峡龙蟠右岸土石混合体的现场水平推剪试验中,得到了一些有益的结论。

| Abstract: | In-situ horizontal push-shear test is a common way to study the mechanical strength of geomaterial.But when it was used in the inhomogeneous geomaterial like soil/rock mixtures and etc,the failure surface may be very irregular.Based on the theoretical analysis of 3D limit-equilibrium method,the computation method of the large-scale in-situ horizontal push-shear test considering 3D sliding surface was inferred,and the corresponding data processing system(HPT-3D) has also been established using VC .NET program,which provides a new processing method for in-situ horizontal push-shear test.Through the application of the method in the large-scale in-situ horizontal push-shear test of soil/rock mixtures in the right bank of Longpan,some beneficial conclusions were obtained. |
