半开挖半护壁施工无大开挖条件的深基坑技术

Protecting wall while excavating the deep foundation without large excavation condition

根据舞阳钢厂炼钢水处理旋流池土石方开挖工程实例,介绍了受场地制约无大开挖条件下,对于大型地下基坑采用半开挖半护壁的技术方法,并对护壁的计算方法进行了详细介绍,希望对类似大型基坑开挖提供一些借鉴。

Combined with the earth and stone excavation of the whirling pool which is used to process steel making water of Wuyang steel factory, it introduces protecting wall while excavating technology which is used in the large underground foundation pit without large excavation condition and elaborates the protecting wall technology, in the hope of offering experience for similar large foundation pit excavation.
