| 摘 要： | 三峡二期工程在上游围堰破堰进水前，发现在大坝上游面存在主要为竖向的裂缝，蓄水后将可能对大坝正常运行造成不利影响。裂缝处理的措施有：化学灌浆、嵌填止水材料、粘贴橡胶片、两侧及上下端防护。裂缝处理后，对施工质量进行了检测，布置了安全监测仪器，监测说明取得了良好效果。

| Abstract: | Prior to upstream weir breaking and water flowing into the foundation pit during the second stage works of Three Georges Project, it was found that there existed mainly vertical cracks on the upstream dam surface which might have adverse effect on the future normal operation of the dam upon impounding. Measures to treat cracks were taken such as chemical grouting, inserted sealing material, rubber waterstop, protection of both sides and upper/ lower ends. After treatment was carried out to the construction quality, and the safety instruments were arranged, which has achieved a good result. |
