Abstract：
In the large deep foundation pit engineering, the soil nailing wall in the upper and the pile anchor supporting in the lower were used; considering effect of time and space, we strengthened foundation pit wall in the central range. Adopting suitable methods, we used partition running water construction in the deep foundation pit and foundation construction, took the earthwork out of deep foundation pit out the pit use by the natural slope. According to soil conditions, we made the hole of supporting pile and engineering pile respectively by long spiral drill stem and rotating drill. After the upper earth excavation, engineering pile were constructed in the pit. Combined with the specific conditions of the construction site , the construction plan was determined, which achieved good
effect.
