| 摘 要： | 缅甸船厂12000DWT干船坞工程在抽水试验井施工过程中发生部分井壁坍塌,究其原因,有地下水动力作用的自然因素,又有桩基础挤土效应、压密注浆等人为诱发因素。通过现场观测和分析,在利用地下水动力作用方向的基础上,采取了改善泥浆性能、预先释放挤土应力等措施后,井壁无坍塌现象出现。经抽水试验验证,成井效果良好。

| Abstract: | During the construction of the Myanmar ship yard 12000DWT dry dock project,a part of wall of wells for pumping test collapsed. The collapse reasons comprised ground water dynamical action, compaction effect of pile foundation, pressure grouting. After taking some measures, including making using of ground water dynamical action, improving slurry performance, releasing the compaction effect of pile foundation and so on, there was no collapse happened and the quality of wells was testified very good by pumping test. |
