摘　　要：针对在实际监测工作中出现应变计拉应变测值过大的现象,本文结合差动电阻式应变计的几何特征、工作原理及其埋设方法,对差动电阻式应变计的测值进行了探讨。We often encounter the problems during actual monitoring work that the tensile strain observed from strain gauge is greater than the ultimate tensile strength of concrete. This paper has discussed the measuring value from differential strain gauge based upon analysis of its geometry, working principle and embedding method.

关 键 词：监测数据 拉应变 差动电阻式应变计
