摘要
根据下涧口水库的工程地质情况,结合水库大坝实际运行状况分析了砌石拱坝存在的主要病害问题,提出了针对坝体拉应力超强、重力墩稳定性不足等方面的除险加固初步方案,在技施设计中分析了初步方案的种种不足并结合工程自身的特点对方案进行了优化设计,使各方面的指标达到了规范的要求,在提高了工程安全性能的同时节省了施工工程量,同时给出了除险加固的具体措施,可供类似工程参考。
According to the engineering geology situation about the Xiajiankou reservoir, this paper analyses the main operation problems combined with the actual running conditions of the dam, and put forward principium program in connection with exceed sufferance intensity of tensile stress and lack stability of gravity frusta for maintenance and strengthening whose shortages are indicated during the construction design. The characteristics of the engineering are used to optimize the program to make every index attain to the requiring of criterion , enhance the safety performance and save the engineering work load at the same time, and concrete mea sures are given for reference to similar projects.
