摘要
考虑有关因素对土压力分布的影响 ,根据挡土墙后土体薄层的竖向平衡条件推导出一般情形下主动土压力分布的一般解 ,并利用实测土压力数据 ,经优化拟合确定解答中包含的 2个参数 。
The general solution of earth pressure distribution is obtained using thin layer equilibrium theory, which considers the effect of concerned factors on earth pressure distribution. Two parameters K w and m of the formula can be computed through programm using optimization technique. A new method to determine the active earth pressure distribution against retaining wall in usual case has been proposed in this paper, which provides a new way to study the question of earth pressure against retaining wall.
