英文摘要	As liquid-storage tanks become larger, it brings many new problems, such as storage tank's tilt, collapse and damage of accessory components caused by unusual settlement; lower safety factor of composite foundation can't ensure the necessary safety reserve for this special structure. Therefore, it is urgent to develop an analytical method for this special structure which is closer to mechanical behavior of practical engineered systems. This paper takes composite foundation treated with compaction piles of Lintao oil depot of PetroChina Gansu branch as the engineering background and simplifies a large number of decentralized piles arranged with regular triangle as a model in which continuous circular piles and compacted soil are arranged alternately, the pile-soil-structure interaction model is established by applying the finite element method. Through the solution of deformation and stability, it shows that the maximum settlement value is smaller than the limit value of standards and the differential settlement can also meet the requirements, the safety factor is greater than the general value which is required 2 in engineering. At the same time, the maximum settlement of composite foundation is calculated by using the theoretical formula, the theoretical solution is close to settlement value calculated by the finite element method, so that the rationality of the simplified method put forward in this paper is verified. © 2015 ejge.
