随着岩石工程建设的发展,实地测试岩体应力状态日益受到重视。岩体应力实测成果的可靠性及其在实际测试中如何评定的问题,是工程设计和岩石力学工作者最为关注的一个问题。本文叙述了我院在研究测试成果可靠性问题时,对CJS-1型钻孔三向应变计所进行的一次模拟性标定试验,并就其试验成果准确性作了评定。试验表明,该应变计有较高的精度,测试成果基本可靠。本文对现场测试中如何评定测试成果的可靠性问题也进行了讨论。
With the development of rock engineering construction, the stress state of the rock mass in the field has been increasingly valued. The reliability of the measured results of the rock mass stress and how it is assessed in actual tests are a major concern for engineering design and rock mechanics. This article describes a simulation calibration test performed on the CJS-1 borehole three-dimensional strain gauge when studying the reliability of the test results, and assesses the accuracy of its test results. Tests have shown that the strain gauge has high accuracy and the test results are basically reliable. This article also discusses how to assess the reliability of test results in field tests.
