-
摘要: 介绍了忠县——武汉输气管道在江汉平原段沿线的自然地理概况, 研究了江汉平原管道沿线的膨胀土、淤泥类土和粉细砂等不良土体的工程地质特性, 统计分析了这些不良土体的工程参数。指出不良土体对管道建设具有潜在的危害性, 提出了符合管道建设的设计和施工处理措施。Abstract: Zhongxian-Wuhan Gas Transmission Pipeline will pass through the Jianghan Plain. The geological property of the adverse soil mass such as expansive oil, soft organic clay and silty and fine sand along the pipeline route is studied and analyzed. It is pointed out that these adverse soil mass potentially hazard the construction of pipeline. The design met the needs of construction of pipeline and protective measures are put forward.
