【摘要】 根据兰成渝成品油管道途经地域的地形和地质特征,在线路设计过程中,在地质条件不稳定地段采取了严格的地质灾害预防措施,通过在山区复杂地段较多地采用隧道,在河流穿越地段加大管道埋深,对跨越结构进行严格的抗震校核,对线路截断阀室进行合理布置等措施,提高了管道的抗震能力。从建筑造型、结构形式、基础和使用抗震构造几个方面进行了站场建筑结构提高抗震能力的设计。更多还原

【Abstract】 Based on the features of terrain and geological area where Lanzhou Chengdu-Chongqing Oil Product Pipeline will pass across,strict countermeasures against geological hazards are taken in unstable geology areas during the process of pipeline route design.These technical measures include that for pipeline sections in mountain area.many tunnels are constructed;in river crossings,buried depth of pipe section is increased;for the overhead crossing structure,aseismic check-up is conducted strictly;for the line block valve chambers,rational allocation is earned out.which increase the aseismic capacity of pipeline.For stations’ construction structures.designs are made in the aspects of construction modeling,structural type,foundation and utilization of aseismic structure in order to strengthen aseismic capacity of these stations.更多还原
