在软土基坑中，放坡开挖将引发坑内工程桩产生偏位和附加弯矩。为尽可能减小基坑放坡开挖对坑内工程桩所产生的不利影响，应对基坑开挖深度进行严格控制，且相比增大坡脚至建筑物底板距离，采用缓坡率可更为有效减小对工程桩产生危害。

In soft soil foundation excavation, slope excavation wil cause the bias and additional moment of engineering piles. To reduce the adverse effect as far as possible of the founda-tion pit slope excavation of foundation piles, should strictly co-ntrol the depth of foundation pit excavation, and compared wi-th increasing distance from bot om to toe of buildings, the ram-p rate can be more effective to reduce the harm to the engine-ering pile.
