前布墩水闸基坑开挖与地基处理方法探讨

Discussions on Qianbudun Water Lock Foundation Ditch Excavation and Foundation Treatmen Method

在木兰溪前布墩水闸工程施工中,针对软土地基特性分别采取浆砌石围堰、喷射砼防渗墙、钻孔灌注桩相结合的综合方法,保证闸室底板及消力池基坑开挖边坡的安全;采取桩基础解决闸室、公路桥基础土层地震液化以及不均匀沉降问题,可为类似工程的建设提供借鉴。

The treatment is expouned in the construction documents of Qianbudun water Lock engineering in Mulan River. Aimed at soft clay, took the integrated methods laying stones cofferdam sprayed concrete impervious wall driu compresd pile Ensured the safety of lock floor snd exeavatain slepe in absorption basin. Took the founda- tion pile to solve the soil earthqnake liqnefacient in lock basin,wagon bridge foundation and toslve the nonuniform settlement. The result can provide valuable reference for other engineering.
