摘要
为研究一种装配叠合式管廊在水平地震力作用下的破坏形态,采用拟静力试验研究方法,基于不同覆土厚度、腋角高度、配筋形式和施工工艺共设计5个装配叠合式管廊进行低周往复荷载试验,分析装配叠合式管廊在模拟地震力作用下的破坏形态并结合设计标准提出工艺改进措施&结果表明:该装配叠合式管廊均发生弯曲破坏,极限位移角在1/27-1/20之间,延性性能好;腋角处、后浇自密实混凝土与预制部分接触面为结构的薄弱部分;提出的工艺改进措施可为实际工程的施工及设计提供参考.
In order te study the failuro mode of a prefabricated superimposed pipe gallero under horizontal,seismic force,the quasi-static test method was used on five prefabricated superimposed tube galleries,which were designed based on the differene thickness of overlying soil,the heighe of 8x1*'angle,reinforcement and ccnstruction technicc.The failure modes of prefabricated superimposed pipe galleries under simulated earthquake force were analyzed and the technical improvement measures were put forward in ccmbination with the design criterions.The resulte showed that,thebendingfailure occurred in theprefabricated superimposed pipe galler,and the ultimate displacement angle was between 1/27 and 1/20,the ductility was good.The ccntact between the post-pouring ccncrete and the prefabricated part was the week part of the structure at the 8x0*0 corner.The proccss improvement meesures proposed cculd provide referencc for the ccnstruction and design of practical engineering.
