摘要
我国的水库数量居世界首位,目前相当多的水库大坝需要除险加固。本文通过对目前我国大坝病害现状和常用加固技术的比较分析,指出SRAP工艺在大坝加固中应用的合理性、实用性以及技术的优越性(修复裂缝、材料无毒性等优点),给出了SRAP工艺在大坝加固中的施工措施及其对维修加固的预期效果。研究结果表明,SRAP工艺结合工程加固数值模拟能指导大坝维修加固,提供的工程措施能够有效防止裂缝和满足维修加固的目标需要。
A large number of reservoirs need be rehabilitated and reinforced in china which is in possession of the most reservoir amounts in the world.So the Korea SRAP approaches were introduced into China by Nanjing hydraulic research institute supported by "948" project of the Ministry of Water Resources of China. As new rehabilitation and reinforcing techniques,the SR strengthen materials and AP modified resin mortars were combined with prestressed method in SRAP approaches.First,nowadays dam distress characteris...
