- 文章结合莫桑比克贝拉油库工程的一座地下构筑物——油水分离器的施工,介绍了在施工场地狭窄、地下水位高、地基软弱的情况下,采用钢板桩进行基坑支护的施工方法,如钢板桩支护方案的制定、支护结构的设计原则及选型、施工工艺流程、技术措施及注意事项。实践证明,采用钢板桩支护,为油水分离器主体的施工提供了一个安全的施工环境,而且工程质量、工期和投资都得到了有效控制。
Taking the underground oil and gas segregator located at Beila Oil Depot,Mozambique,as an example,this paper describes the construction methods of using steel sheet piles for foundation pit support in the unfavorable conditions including narrow construction site,high underground water table,soft and weak foundation,with respects to the support scheme establishment,design principle and type selection of the support structure,the construction process flow,technical measures and matters for attention.The engineering practice has proved that using steel sheet piles for foundation pit support provided a safe construction circumstance for main part construction of the segregator,and controlled the construction quality,period and costs effectively.2009,4(4): 38-41 收稿日期：2008-11-30分类号：TU473.13作者简介：吕玉宏(1973- ),男,河南兰考人,工程师,1996年毕业于中国石油大学(华东),一直从事土建施工技术管理工作.?参考文献：
