摘　　要：以实际工程为例,针对紧邻建筑物的深基坑,采用预应力钢筋混凝土护坡桩作为挡土支护结构,有效提高了支护结构的强度和刚度,且护坡桩设计中土压力的计算方法,对类似深基坑支护工程的设计计算具有一定的指导和借鉴作用。In the deep foundation supporting, widely using the cast- in- place reinforced concrete to retain the earth supports and proteetions structure . in this paper, according to one instance of engineering project, to deep foundation pit in the proximate building , using the slope protection pile of prestressed reinforeecl concrete, prestressed steel stranded wire in the pile has improved intensity and therigidity of supporting structure effectively , and the computational method of earth pressure has certain instruction and model function to the similar deep foundation supporting engineering design calculation .
