对大坝渗压监测中两个问题的看法

从论述渗压监测的重要性出发,提出对大坝渗压监测中两个问题的看法.土石坝安全监测技术规范中不应以坝高和渗压滞后作为限制采用测压管的理由,采用何种监测方式应注重实际效果;对渗压监测仪器就灵敏度、精度、长期稳定性等多项指标进行讨论,指出长期稳定性应作为埋设仪器选型的主要指标.

Opinions on the two problems in seepage pressure monitoring

In this paper opinions are put forward on the two problems in seepage pressure monitoring for dams in regard to its importance. The authors think that it is untenable for restraining the application of slotted-pipe piezometer by dam height and delay reaction ruled in the technical specification for fill-dam monitoring. The appropriate methods used should be selected upon practical effects. Furthermore, the sensitivity, accuracy and long period stability have been discussed, the performance of long period stability is preferred as embedding instruments selection.
