摘要
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 considering the interaction between adjacent plates, based on theory of four-side free rectangle plate, the interaction among adjacent foundations and soil was studied. Making use of the solution of four-sides free rectangle plate under external loads action, counter force of soil and generalized displacement on the boundary of plate, the interaction compatible formulas of force, and displacement taking account of interaction among adjacent rectangular foundations and subsoil were obtained. The interaction calculation results of engineering example proved that the method presented in this paper accorded with measured data. The results indicated that the load of adjacent rectangular foundation had an important influence on the results of foundation settlement, ground counter force and the moment of foundation plate. The settlement coefficient considering the ratio between distance and width was presented finally.
