深厚软土大型油罐搅拌桩复合地基试验研究

Experimental Study on Composite Foundation of Deep Mixing Cast-in-situ Piles for Large Oil Tank on Soft Clay

本文结合国家石油储运舟山岙山基地成品油罐区4个10000m3油罐的实践，对采用搅拌桩复合地基加固深厚软土建大型油罐问题进行试验研究，简单介绍了设计方法和实施情况，对室内试验和现场测试结果进行了详细分析，提出了一些有价值的结论。

Using deep mixing cast-in-situ pile is a kind of soft ground treatment method for improvingengineeing foundation. In this paper, the experimental study of the composite foundation of deepmixing piles for large oil tank on soft clay has been carried out through the proect of 10000m3 oiltank in Zhoushan. The design method and the implementation conditions are simply introduced.The indoor test results and in-situ measurements are analyzed. Finally, some valuable conclusionsare drawn.
