随着现代工程建设项目的大量兴建,都迫切需要测定建筑物场地的物理力学特性。特别是类似核电站、地热开发以及防护工程的兴建,要求测定离地面百米以下岩体内部的动力特性,对于这些特殊要求,采用一般的测试技术已无能为力。本文根据某重点工程现场地基物理力学特性的测试技术,介绍一种大跨度测定岩体横波波速的方法。一、问题的提出我们知道,岩石是脆性材料,其破坏因素主要受剪切力的影响。由弹性理论知道,
With the large-scale construction of modern engineering construction projects, there is an urgent need to determine the physical and mechanical properties of the building site. In particular, the construction of similar nuclear power plants, geothermal development, and protective engineering requires the determination of dynamic characteristics within the rock mass below 100 meters from the ground. For these special requirements, the use of general testing techniques has been ineffective. Based on the testing technology of the physical and mechanical characteristics of the foundation of a key project, this paper introduces a method for measuring the shear wave velocity of rock mass over a large span. First, the issue is raised We know that rock is a brittle material, and its destructive factors are mainly affected by the shear force. Known by elasticity theory,
