| 摘 要： | 放坡开挖适用于地基土质较好、开挖深度不深，以及施工现场有足够放坡场所的工程。本文讨论了软土基坑施工中，当开挖不深(3～5m)、基坑开挖对周边工程环境要求不高或有可靠措施时采用放坡开挖的技术参数，列举了工程实例。

| Abstract: | Step-slope excavation is suitable for the project of which the foundation has better soil properties,lower excavation depth or enough site space for step-slope.This paper discussed the technical parameters and field example project of safety foundation pit by step-slope method when the foundation excavation was not deep,had less influence on the surrounding environment or had some reliable measures to prevent collapse. |

| Keywords: | step-slope foundation pit critical depth slippage stable factor |
