为了计算相邻基础板之间的相互影响,基于四边自由矩形板理论,对地基上的相邻基础与地基共同作用进行分析,在四边自由板在外荷载、地基反力和板边广义位移共同作用下产生的位移解基础上,通过建立基础板与地基之间的力与位移协调方程,得出相邻基础与地基共同作用的解析分析方程。并通过与试验数据对比验证该方法的可靠性,在此基础上对相邻基础不同间距情况下的共同作用进行计算比较,结果表明相邻基础的荷载对于基础沉降、地基反力的分布、基础板的弯矩等都有较大的影响。最后给出相邻基础距离与基础宽度比对共同作用沉降计算结果的影响系数。
In order to calculate the mutual influence between adjacent base plates, based on the theory of free rectangular plates on four sides, the interaction between adjacent base and ground is analyzed. In the four outer plates, the external load, the reaction force of foundation and the generalized displacement Based on the displacement solution, the analytical equation of the interaction between adjacent foundation and ground is obtained by establishing the coordination equation of force and displacement between foundation plate and foundation. And compared with the experimental data to verify the reliability of the method. Based on this, the interaction between adjacent base under different pitches is calculated and compared. The results show that the load of adjacent basement is good for the foundation settlement, the distribution of foundation reaction force, Bending moment of the board has a greater impact. Finally, the influence coefficient of the interaction settlement between the adjacent foundation and the foundation width is given.
