大坝位移监测分析及稳定性识别研究

Analysis of Monitoring Displacements From A Large Dam And Its Stability Identification

本文应用确定性力学来分析大坝的位移监测资料，将反分析技术引入到大坝的安全施工和运行监控中并进行工程的稳定性识别评价。在反分析中作者提出了一种新的岩体多介质弹模识别方法。以湖南东江拱坝的位移监测为研究课题进行了具体的分析和稳定性评价。最后作者提出了一种简便快速的预测评价方法，两者结合应用，使监控工作既快又实用，值得现场技术人员使用。

In this paper the deterministic mechanics models are used to interpret measured displacements from a large dam,and back analysis techniques are incorporated into the safety construction and operation monitoring of a large dam to identify its stability state.A new technique is presented in this paper for identification of multi-material elasticity moduli.A detailed study has been carried out on the displacements measured in the Dong Jiang arch dam in order to specify the procedure of monitoring analysis and stability assessment of a large dam.Finally,a simple method is proposed for rapid prediction of the working performance based on measured displacements in a large dam in conjunction with the deterministic and it is worthy of popularization in engineering practice.
