摘　　要：探讨了在紧邻桥桩的情况下基坑的支护型式,对挖孔桩+横撑、桩锚等2种支护型式下基坑开挖进行数值模拟,重点探讨了2种支护型式下桥桩位移、基坑位移;另外也从施工角度及造价角度探讨了2种支护型式的合理性。对类似工程有一定的借鉴意义。This article discusses the supporting pattern of the pit which is next to bridge piles,and the numerical simulation of pit excavation is carry out under the two supporting types of dug pile ＋ crossbars.piles anchor. It focus on probe displacement of the bridge pile and pit under the two supporting types. In addition, it explore the justifiability of two supporting types from the point of construction and cost. It have a certain significance for the similar projects.
