| 摘 要： | 第一溢洪道是密云水库的重要泄水建筑物,建成后10多年在闸墩上发现了大量裂缝,成因为温度应力所致,后采用环氧灌浆进行处理,并埋设电测仪器进行观测。通过30 a来的观测成果进行系统分析,表明闸墩运行状况良好,当时采取的工程措施合理有效,但也存在一些问题需要解决。

| Abstract: | The first spillway is an important water release structure in Miyun Reservoir.After 10 years in operation many cracks caused by thermal stress were found in its piers.The cracks were treated by epoxy resin grouting meanwhile electrical measuring instruments were installed to observe the stress changes.Through observation data analysis of 30 years,the results show that the piers of the spillway have been in good operation condition and the treatment measures proposed then were suitable and effective. |
