复杂条件下基坑支护设计研究

Research on Design of Foundation Pit Support in Complicated Conditions

介绍某深基坑工程范围内存在的既有排水暗渠所造成的复杂的场区边界环境及基坑支护的设计.通过对现场的实际勘察及相关理论分析,施工期间对既有排水暗渠进行临时支撑,且对不同的支护面采用排桩、锚索和土钉墙分别进行支护,较好地解决了既有暗渠、深基坑支护的稳定性及安全性等问题,并提出了相应的施工建议,对于类似工程具有一定的参考价值.

It describes that a drainage culvert in the range of a deep foundation pit engineering brings difficulty to the design and the construction. Based on the practical investigation and theoretical analysis, temporary support is used to guarantee the stability of the drainage culvert during the construction period. Because of the narrow construction site and the complex environment conditions, different supporting technologies are applied, and this could make the engineering much safer and engineering cost much lower. Meanwhile some corresponding suggestions on construction is put forward. Finally it can give a certain reference for similar projects.
