丹江口大坝27^(#)、31^(#)重点坝段安全监控性态分析

Safety analysis on No.27,No.31 monoliths of Danjiangkou Dam

丹江口大坝27#、31#坝段位于厂房坝段,其基础位于F185、F609构造破碎带交汇区,是重点监测坝段之一。从1989年起对两坝段实施在线监控,根据电测资料建立了单、多测点统计模型,对27#、31#坝段的安全性态进行了综合性分析及评价,结果认为大坝运行是安全的。

The No.27 and No.31 monoliths of Danjiangkou Dam lie in the power house monolith, their foundation is in the intersection area of tectonic crushed zone, and this monolith is one of the main monitoring ones. Since 1989, on?line monitorings have been carried out at the two monoliths. Single point and multiple point statistical models are founded on the basis of monitoring data, and then the general safety analyses on No.27 and No.31 monoliths are done by using these models results. From the analysis, the operation of the dam is safe.
