摘要
西气东输管道工程全线所经场地地震烈度Ⅵ度区有 2 2 4 2 .1km ,Ⅶ度区约 1184 .5km ,Ⅷ度区约 4 6 7 4km ;经过地震断裂带 8条 13个交叉点 ,为保证管道安全 ,在遇到地震影响时 ,为避免或减少管道的破坏和防止发生次生灾害 ,应对管道通过上述危险地段进行抗震计算 ,以最少的工程措施来保证工程的安全。文章通过计算得出 ,全线 390 0km只有一处地震断裂带与管道交叉处需要进行局部改线就能满足安全要求 ,而其余地段均是安全的结论。
The West-to-East Gas Pipeline will cross a few seismic zones,2242.1 km of it will cross a seismic zone with a seismic intensity of Ⅵ,1184.5 km with a seismic intensity of Ⅶ and 467.4 km with a seismic intensity of Ⅷ.It will cross 8 seismic fracture belts with 13 crossing points.In order to ensure safety of the pipeline,anti-seismic calculations have been taken to reduce damage to it as far as possible.Calculation results show that there is only one seismic fracture belt where the pipeline shall make a detour and other of it is safe.
