现场岩体弹性常数的测定,对于了解岩体的属性,探讨岩体破坏机理,有效地解决工程问题,具有十分重要的意义。但是这项工作即费时又费事,所用的工具一般比较笨重,测得的结果也不够精确。为此,我们进行了改革,采用较为轻便的拉拔器作为现场弹性常数测定的主要工具。即以拉拔器通过锚杆对岩体加载,配以千分表 The determination of elastic constants of on-site rock mass is very important for understanding the properties of rock mass, exploring the failure mechanism of rock mass and effectively solving engineering problems. However, this work is time-consuming and labor-intensive. The tools used are generally cumbersome and the results obtained are not accurate enough. To this end, we conducted a reform, using a more portable puller as the primary tool for determining the elastic constants in the field. That is to puller rock bolt through the load, with a dial gauge
