| 摘 要： | 国家重点工程西部管道工程兰州原油末站超大型油罐群,是我国首次在高饱和度黄土地基修建的超大型储油设施。由于高饱和度黄土地基天然承载力过低,仅为60 kPa,油罐区地基采用CFG桩复合地基进行处理。通过现场CFG单桩及单桩复合地基静载荷试验,确定复合地基承载力,并对该种地基处理方法进行评述,为该地区地基处理积累了工程经验。

| Abstract: | The large oil tank group in Lanzhou,which is a part of the state key project-the western oil pipe line project,is constructed on the saturated loess stratum for the first time in China.Due to lack of bearing capacity,the CFG method is used in the foundation treatment of the saturated loess.Through the in-situ tests for the CFG single pile and the static loading,the bearing capacity of the composite foundation is defined,and the foundation treatment method is discussed to provide references for similar proje... |
