摘要
结合上海外高桥四期工程地基加固,对井点降水联合低能量强夯法在吹填细砂和下卧扰动软土层双层地基加固中的应用进行了现场试验研究,对试验检测数据进行了整理分析,并提出了大面积加固时的施工工艺。试验结果和工程实际应用,获得了较好的效果,进一步证明了强夯新工艺对饱和软粘土地基加固处理的适用性,并从工艺角度进一步完善了该套工艺的技术参数内容,可供类似工程参考。
This paper introduces a site test and application of low-energy DCM in combination with well dewatering with respect to the enhancement of soft foundation of Shanghai Waigaoqiao Phase IV Project, in which based on the profound analysis of the test data, the construction technology for large-area enhancement of soft foundation is proposede. The results of both experiment and engineering practice further proved the adaptability of DCM for enhancement treatment of saturated soft clay foundation and enriched the contents of technical parameters of the DCM technology, which can serve as a reference for similar engineering
