- 西气东输二线西段管道工程第9A标段沿线有42 km穿过酒泉市农田灌溉地区,地质类型主要为粉质黏土,湿陷性较强。根据设计要求,该段主要采用浆砌石堡坎和草袋子堡坎两种水工保护形式,文章通过关键工序的控制,介绍了如何避免和解决在湿陷性粉质黏土地区进行水工保护施工出现的如裂缝、沉降不均和流水冲刷的问题,经过在西气东输二线工程中的应用,取得了较好的成效。
The 42 km long pipeline in the 9A bidding section of West Section of Second West to East Gas Pipeline Project passes through irrigation farm region of Jiuquang City, where the geological category is mainly of silty clay with stronger collapsibility. According to the design, two hydraulic protection ways i.e. using mortar laid stone barriers and straw bag barriers are adopted. Through controlling key processes, the measures avoiding and treating the problems such as cracks, uneven settlement and water scouring that occur in hydraulic protection construction in collapsible silty clay region are presented. The practical application in Second West to East Gas Pipeline Project achieves good results.2010,S1(S1): 280-282 收稿日期：2010-9-27分类号：TE973作者简介：岳玉民（1956-），陕西华阴人，高级工程师，1993年毕业于中央党校行政管理专业，现从事管道工程项目管理工作
