西气东输三线东段第二标段站场边坡设计与施工

Station slope design and construction of second bidding section of Third West-East Gas Pipeline

西气东输三线管道东段工程第二标段总共设置8座站场,其中需要边坡处理的就有6座。这6处边坡中,挖方最大高差28 m,填方最大高差24 m,处理难度较大。首先分析了该工程中边坡设计的特点,而后简要介绍了边坡工程常见处理方案,在此基础上,以泉州站边坡设计施工为例,详细介绍了工程概况、地层条件、设计方案、主要施工技术要求、设计方案实施效果等,最后指出,由于站场选址受限越来越严重,以后会出现更多的高边坡工程,因此应单独针对这些高边坡工程,进行专项设计施工,这样才能真正处理好边坡问题。

There are total eight stations in the second bidding section of the Third West-East Gas Pipeline.Among them,slopes at six stations are required to treat.The treatments include soil filling and excavation.The maximum height of filling is28m and the maximum height of excavation is24m,which are all difficult to deal with.This paper summarizes the characteristics of slope design in this project,and takes the Quanzhou station as an example to expound the slope design in detail,including the project outline,stratum condition,design scheme,main techical requirement of construction,implementation of design scheme.It also puts forward that facing more and more slope projects in future,special design and construction for complex slope engineering should be researched,and this is the only way to achieve the purpose of slope engineering.
