在高坝整体稳定地质力学模型试验中,针对目前存在的结构面相对位移测试问题,采用应变测试技术,研制了用于获取结构面相对位移的测试仪器。测试时,用应变仪记录不同加载条件下相应测点的应变变化过程,再由埋设之前标定的位移和应变系数即可得出位移变化过程。通过小湾和大岗山拱坝整体稳定三维地质力学模型试验中的成功运用,表明该仪器结构设计合理,制作和使用方便,测试准确。

In the geo-mechanical model test of high dam's global stability,and aiming at the test problem of the relative displacement of structural planes,the strain testing technology is used to develop a kind of measuring instrument as mentioned above.In the test,strain gauges are used to record the strain changes of measurement points under different loading conditions,then according to the coefficient between displacement and strain,the process of relative displacement changes is obtained.Through the successful application of the test instrument in 3-D geo-mechanical model test for the global stability of Xiaowan and Dagangshan high arch dam,it is indicated that the structure of the measurement instrument is reasonable,the manufacture and use of it are easy,and the test result of it is accurate.
