摘　　要：采用土工有限元软件PLAXIS 8.2对地面堆载作用下邻近的桩基性态进行二维有限元分析,研究了单排桩、双排桩在地面堆载荷载大小与作用位置、桩与土层条件、桩身约束条件等工况中的性状。The geotechnical finite numerical analysis software Plaxis 8.2 was used to simulate the behavior of piles influenced by the soil movements from a nearby surface loads. Piles were represented by equivalent sheet-pile walls. The soil-pile interaction effects of surcharge loads, pile conditions and soil layer conditions were studied.
