针对目前高层建筑箱型基础基底反力计算所存在的问题,在弹性地基理论的基础上对地基土的压缩模量进行了非线性修正,并对地基沉降进行几何平面调整处理,提出了基底反力的迭代计算方法.该方法能对任意平面形状的箱型基础进行基底反力、沉降量和整体倾斜量计算,并且能同时考虑相邻建筑物、地基土分层、地基土平面不均匀和基坑周边土性变坏等影响;该方法迭代收敛快,计算结果与实测结果相符,不用求解高阶代数方程,适合于手算或电算.文中给出计算机程序框图,便于在计算机上进行计算.
Aimed at the problems existing in the calculation of basement reaction of high-rise building box foundations, based on the theory of elastic foundations, nonlinear correction of the compressive modulus of foundation soils was carried out, and the geometrical plane adjustment of foundation settlement was proposed. Iterative calculation method of force. This method can calculate the base reaction force, settlement amount and overall tilt amount for any box-shaped box-shaped foundation, and can simultaneously consider the adjacent buildings, the foundation soil layering, and the unevenness of the foundation soil plane. The influence of soil deterioration around the foundation pit; this method is fast iteratively convergent, the calculated results are consistent with the measured results, and it is suitable for hand calculation or computer calculation without solving the high-order algebraic equations. The computer program block diagram is given in the paper, which is convenient for computer Calculation.
