本文论述了如何用仪器观测资料确定浸润线位置和管涌分析判断的两个主要土坝渗流安全问题。在总结工程实际经验的基础上,在指出了常规仪器监测的局限性和必要性的同时还强调了对坝区进行经常检查巡视的重要性。文末,还对土坝渗流安全监测工作提出了一些看法。一、引言我国水库所垮土坝由于渗流方面的原因占垮坝 This paper discusses how to determine the location of pipelines and the seepage safety problems of the two main earth-rock dams based on the observation data. On the basis of summarizing the practical experience of the project, pointing out the limitations and necessity of routine instrument monitoring, it also emphasizes the importance of frequently inspecting and inspecting the dam area. At the end of the article, some opinions on earth dam seepage safety monitoring are also put forward. I. INTRODUCTION Due to seepage, the earth-rock dam in our reservoir accounts for the collapse of the dam
