木兰溪前布墩水闸基坑开挖与基础处理方法

在木兰溪前布墩水闸工程施工图设计时，针对复杂的地形、地质条件，分别采取浆砌石围堰、喷射混凝土防渗墙、钻孔灌注桩相结合等综合方法，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它们之间的不均匀沉降问题，为该工程保质保量顺利完成奠定了的基础，取得了良好的经济和社会效益。

Foundation Ditch Excavation and Foundation Treatment Method of Qianbudun Water in Mulan River

The treatment is expouned in the construction documents design of Qianbudun water Lock engineering in Mulan River. The sophisticated landform and geology condition are aimed. The integrated, methods laying stones cofferdam sprayed concrete impervious wall are drive-in compressed pile, The safety of lock floor and exeavatain slope in absorption basin are ensured. The foundation pile to solve the soil earthquake liquefacient in lock basin, wagon bridge foundation and to solve the nonuniform settlement between them are taken. The design laids a good foundation on the quality and quanity guaranteed of the engineering, and has made good economy and social benefits.
