Abstract: This paper introduced the monitoring on seepage for TGP’s left power plant building (left non-spillway) monolith. The monitoring result demonstrated that the osmotic pressure, seepage uplift and seepage quantity in dam body increased visibly after upper and lower coffer wall removal and water storage, but under design requirement. The result provided important scientific reference for the safety in stage of construction and operation of TGP. Moreover, it will optimize the design of TGP.?

摘要: 本文主要介绍三峡工程大坝左厂(非)坝段落流监测工程,监测成果表明,上下游围堰破墟和大坝蓄水后,坝基(体)渗压、坝基扬压力和渗流量等多有明显增加,但均在设计允许范围内。渗流监测成果为三蛱工程的施工及运行安全、优化设计等提供了重要的科学依据。
