长输管道盾构隧道地质勘察设计

Geological Survey with Shield-driven Tunneling Technique for Long distance Pipeline Design

介绍了盾构隧道管道穿越特大型河流地质勘察在方案设计、初步设计、施工图设计和施工印证勘察四个阶段中的勘察项目和方法,详细说明了盾构穿越断面所通过的崩塌性沙层、高水压区的含卵石砾层、软弱粉质粘土层、含有缺氧层和有害气体等特殊地层的勘察内容和要求。

This paper introduces the survey program and technique involved in the scenario design,initial design, construction drawing design and construction confirmation survey for pipeline crossing extra-large river with shield-driven tunneling technique, describes in detail the survey items and requirements with this technique to cross the special formation,like the avalanche sand fault,pebble sandstone fault of pressurized water zone,etc.
