摘要
通过方案对比,推荐了一种基于点面组合的整体式TS型三向测缝计的构造、计算和误差分析方法,解决了TSJ型三向测缝计测量高混凝土面板周边缝位移精度和安装等问题。该仪器可以通过刚体将面板上的位移点移至空间任一点,从而解决了面板沉降对周边缝三向变形的影响问题,且安装方便,观测精度高。
On the basis of comparison, recommended is a new conformation of TS-style triaxial ioint meter based on dot-surface mix, as well as its calculation method and error analysis. The measurement precision, installation and other problems of TSJ triaxial joint meter in the measurement of peripheral joint＇ s displacement of high concrete-faced rockfill dam are solved. With the instrument, the displacement point on the face can be moved to any point in space, and thus the effect of face settlement on triaxial deformation of a peripheral joint is removed. The installation of the instrument is convenient and the measurement precision is high.
