摘 要:南水北调中线工程北京段惠南段~大宁段采用2排直径4 m的PCCP管道,管道单线总长50 km。管线需穿过西甘池隧洞和崇青隧洞。西甘池隧洞埋深浅、地质条件复杂,为此,比较了钢筋混凝土衬砌、钢板衬砌和洞穿PCCP管结构3种方案,最终采用洞穿PCCP方案。现工程基本完工,表明该方案可行。Two lines of Pre-stressed Concrete Cylinder Pipe (PCCP) with the diameter of 4m and the total length of 50 km each were used in Huinan-Daning section of the South to North Water Transfer Project Middle Route in Beijing area. The pipeline should pass through the Xiganchi and Chongqing tunnels. Because of shallow buried depth and complex geological conditions of the Xiganchi tunnel, three alternatives of reinforced concrete lining, steel plate lining and PCCP passing through the tunnel have been compared, and then the final alternative was adopted. Now the project has been completed basically, which showed such alternative is feasible.
