摘要
介绍了管道通过云南省寻甸县境内9度区和小江断裂的概况,提出了本区段管道的抗震设计方案,包括抗震目标、线路、站场、电力、通讯等系统各组成部分的校核结论,同时引进了地震监测和预警系统。从地震区域背景、性能目标和设防标准、设计方法和手段、材料选择、敷设方式、通信方式、地震监测和预警等方面,将本管道工程与阿拉斯加管道的抗震设计进行系统比较,确认本区段的抗震设计方案是有效的,解释了小江断裂不采取与阿拉斯加管道相同的架空敷设方案的原因,可为途经9度区及断裂带管道的抗震设计提供参考。
The total conditions of a pipeline crossing in the seismic intensity IX area and the Xiaojiang Fault in Xundian,Yunnan Province,is introduced.Relative aseimatic design scenario for the pipeline crossing the area is given,including the conclusions verified to the systems consisted of aseismic structure,pipeline route,stations,power and communication,etc.,and the scenario to be launched will rely on the seismologic monitoring and warning system introduced.A contrast between the pipeline and Alaska pipeline is made from the seismic region background,functional objectives and fortifying codes,design method,material selection,pipe laying mode,communication mode,seismic monitoring and early-warning.It is affirmed that the anti-seismic design in these areas is valid and efficient.Other than the Alaska pipeline,the pipe laying method of the pipeline adopted is a buried laying method to cross the Xiaojiang Fault,which is of great significance for the aseismic design of pipeline to pass through the seismic intensity IX area and fault zones.
