随着地下建筑工程的发展,砂浆锚杆的应用越来越广泛。在工程实践远远走在对锚固机理性认识的前面的今天,现场实测工作显得非常重要。过去的十年间,国内在使用电测量测锚杆测量锚杆轴向受力方面做了大量工作。但是,电测量测锚杆存在着以下两方面问题使得它的应用受到限制。其一,在井下工作半年至 With the development of underground construction, the application of mortar anchor is more and more widely. In engineering practice is far away from understanding the rationality of the anchoring mechanism in front of today, field measurement work is very important. In the past ten years, a great deal of work has been done in the field of measuring the axial force of the bolt by using the electric measuring bolt. However, there are two problems with the electrical measurement of the bolt so that its application is limited. First, the work in the underground half a year
