| 摘 要： | 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。

| Abstract: | In soft soil foundation excavation, slope excavation will cause the bias and additional moment of engineering piles. To reduce the adverse effect as far as possible of the foundation pit slope excavation of foundation piles, should strictly control the depth of foundation pit excavation, and compared with increasing distance from bottom to toe of buildings, the ramp rate can be more effective to reduce the harm to the engineering pile. |
