摘　　要：论述的深基坑工程,采用无砂混泥土桩—预应力锚杆支护结构,地下水处理采用无砂混泥土桩—高压旋喷桩—预应力锚杆铸成的落底式竖向截水帷幕和坑内管井抽水疏干持力层—卵石、圆砾含水层中地下水等一系列措施,保证周边建筑物的安全,对复杂环境下城市工程施工有一定的借鉴价值.The deep excavation was supported by the structure of no-sand concrete pile and priestess earth anchor. The groundwater of the pit-outside was processed by the water-proof curtain which was composed of the no-sand concrete piles, jet grouting piles and priestess tieback, and one of the pit-inside was dewatered by the well in the sustaining layer-cobbles and fine gravels a series of measure of etc, that guaranteed the safety of the peripheral building, and gave certainly draw lessons to complicated environment next the city engineering construction from the value.
