高拱坝坝基变形影响深度的监测方法研究及应用

On monitoring method of affected depth in deformation at dam foundation of high-arch dam and its application

针对高坝坝基变形影响深度尚无监测仪器和方法的问题,提出了多点式监测方案,并阐述了该方案在小湾水电站工程中的实施方式,指出该监测方案取得了可靠的变形监测资料,有助于掌握和评价大坝的安全性。

According to the problems in deficient monitoring devices and methods in the affected depth of the high dam foundation,the paper points out the multiple-point supervision scheme,illustrates the implementation approach of Xiaowan Hydropower Station,and points out the monitoring scheme achieves reliable deformation monitoring documents,so as to master and evaluate the safety of the dam.
