基于Mindlin位移解的群桩沉降计算

Pile Groups' Settlement Calculation Based on Mindlin Displacement Formula

利用Mindlin位移解 ,推导了不同形式 (矩形、正三角形、倒三角形、正梯形、倒梯形等 )的桩侧摩阻力在地基土中引起的位移公式 ;对不同桩长、桩距、桩侧摩阻力的群桩沉降提供一种计算方法。实例分析表明 。

In this paper, the author derives formula induced by different pile's skin frictional drag and pile tips force, using Mindlin's displacement result. The author gives a method to compute the pile group's settlement under different pile's length, distance between piles and pile's skin frictional drag. Through an example's analysis, the computing result is more appropriate than Mindlin's stress result.
