摘　　要：排水工程是一个城市很重要的一部分,一流的城市会建设相当优秀的给排水网工程。现在的城市化建设发展迅速,高楼大厦迅速崛起。一个城市的安全不仅取决于建设的高楼,也取决于埋藏在地下的一些小细节。有一句话是＂细节之处见高低＂,因此,做好每一个细节是事情成功的重要一步,同时也是成功的关键。本文主要结合城市化进程中的现状,探讨和交流给排水网管设计的原则,从而更好的改善和促进我国给排水网的建设。Using ANSYS Workbench established thel~nal-stress analytical model, this paper analyzed the operating period stability of the di- version tunnel lining of Xinjiang Taxkorgan River Qirehataer Hydropower Station under the conditions of high geothermal, high crustal stress and 311.49 m pressure head. The results show that the heat insulation layer can obviously improve the force situation of concrete lining, the average stress of lining decreases about 46%, but the average displacement of the lining structure increases about 14% ; it can significantly improve the safety of the first phase of the concrete after setting the insulating layer, except the two corners＇ safety factors are greater than 1, the rest parts of the structure＇s safety factors are smaller less than 1; the supporting structure, constituted by heat insulation layer, primary concrete and secondary concrete, is reasonable, it can meet the requirements of engineering safety only it improves the tensile ability of retaining structure by using reinforced concrete structure or high performance concrete.
