盾构施工穿越大型河流的技术研究及应用

Technical Research and Application of Shield Construction Through Large Rivers

无锡市地铁1号线和2号线施工中迄今已4次穿越地质条件复杂的京杭大运河。穿越运河风险较大,在高风险的施工环境下,通过合理地安排、科学地组织对盾构施工过程中各项参数、盾构穿越运河不同部位的研究,顺利地穿越了京杭大运河,在施工过程中积累的经验为以后盾构穿越河道起到借鉴作用。

Subway Line 1 and Line 2 have been constructed four times so far through Beijing-Hangzhou Grand Canal with complex geological conditions. It has great risks to cross the canal. In the construction environment of high risks, the project crossed through Beijing-Hangzhou Grand Canal smoothly through reasonable arrangement and scientific organization of the shield construction process of various parameters and shield parts, and accumulated rich experience for a reference for the project of shield through rivers in the future.
