| 摘 要： | 对地面大面积堆载情况下桩基础的计算方法作了一些探讨,以一具体工程为实例,用有限元法计算了桩基础在大面积堆载情况下的地基沉降及桩身的变形情况.结果表明,在软土地区,由于堆载致使地基下沉及桩身变形,作用在临近桩上的荷载会增加,这必然会引起基础的不均匀沉降和建筑物的倾斜.

| Abstract: | The calculation method of pile foundation with extensive accumulation adjacent is discussed. The method is applied to an engineering example, the subsidence of the ground and the deformation of piles are given . From the results some useful conclusion can be drawn as follows: for the pile foundation with extensive accumulation adjacent in soft ground district, due to the subgrade's subsidence and the adjacent piles' deformation, the load acting on piles will be increased. In the end it may cause nonuniform settlement of foundation and tilt of construction more seriously. |
