| 摘 要： | 采用ANSYS有限元程序建模方法,主要对弹性范围内的微型桩进行模拟,选取单桩、两桩、6桩和9桩计算在不同桩距（2d、3d、4d、5d）、不同桩长下的桩基沉降,得出折减系数。模拟研究认为：无论桩的长短,随着桩距的增大,群桩折减系数都在减小;桩距不变时,桩长相等的群桩,桩数的变化基本不引起群桩折减系数的变化。

| Abstract: | The modeling method with the ANSYS finite element program is used to simulate the micro-piles within the elasticity range,with a single pile,two,six,and nine piles chosen,the settlement of the pile foundation with different pile spaces and different pile lengths calculated,and finally the reduction factors obtained.The simulated results show that with the increase in the inter-pile space,the reduction factors for the micro-pile groups will become smaller no matter the piles are long or short.With the inter-pile space remaining the same,and all the piles of the micro-pile group being the same in length,the change in the number of the piles basically does not cause the change of the reduction factor for the pile group. |
