为加强病险水库治理与加固工作,以彰武县长坨子水库为研究对象,分析水库加固现状发现坝高明显没有达到设计要求,存在严重安全隐患,输水洞已经无法正常运行。经过计算,在水库加固中,修整土坝,上游边坡为1∶3,下游边坡为1∶2.50,主坝长度660m,副坝设计修建护坡长度750 m,同时新建棱体排水体,加固输水洞,确保水库的正常功能。
In order to strengthen the management and reinforcement work of dangerous reservoirs, taking Changtuozi Reservoir in Zhangwu County as the research object, it is found that the dam height obviously did not meet the design requirements when analyzing the status of reservoir reinforcement. There are serious potential safety problems and the water conveyance tunnel can no longer operate normally. After the calculation, in the reservoir reinforcement, the earth dam is trimmed. The upstream slope is 1: 3, the downstream slope is 1: 2.50, the main dam is 660m, the auxiliary dam is designed to construct a slope protection length of 750m. At the same time, a new prism body drainage body is reinforced Water hole, to ensure the normal function of the reservoir.
