某大坝安全监测资料的反馈分析

Feedback analysis of a certain dam safety monitoring data

为了全面了解和监控枢纽的建设和运行情况,特别是拦河大坝的变形、渗流及应力发展,枢纽中埋设了大量观测仪器并进行了持续的监测,并取得了丰富的观测资料,这些资料为该坝的反馈分析提供了必要的基础。根据大坝监测资料整理及分析成果,对某心墙堆石坝进行了有限元变形渗流反馈,并预测和评价坝体今后的变形和渗流安全。

In order to fully understanding and monitoring the construction and operation of hydro-junction,especially the deformation, seepage and stress development of the weir dam, a large number of observation instruments are buried in the hydro-junction. Then a large of observational data is obtained by the continuous monitoring of instruments, which could provide the necessary basis for the feedback analysis of the dam. Based on the collation and analysis results of dam monitoring data, the finite element deformation seepage feedback is made for a certain core rockfill dam, finally the future dam deformation and the seepage safety is forecasted and evaluated.
