摘　　要：通过某基坑工程实践,表明大面积两层地下室软土基坑在相对开挖深度较浅且周围环境较好的条件下采用一道钢筋混凝土支撑结合排桩支护是可行的。由于仅设置一道支撑,支撑竖向位置布置比较低,因此浅部土层开挖稳定性要充分考虑。软土基坑侧向变形受施工时间影响很大,地下室施工应严格控制施工暴露时间。The excavation engineering example of Jinrui-Square in HangZhou is introduced： The second floor foundation of soft clay in a relatively shallow depth excavation support the use of one layer reinforced concrete combined together pile support if the surrounding environment are better. Because the vertical position of support is relatively low, so the stability of shallow soil excavation should be fully taken into account. Lateral deformation of soft clay foundation strongly influenced by the timing of construction, the basement of the construction works should he tightly controlled exposure time.
