摘要
把地基分成c型土地基和φ型土地基,利用考虑地基土应力状态的临界荷载计算程序,以及考虑地基土应力状态的深度修正临界荷载近似计算公式,得出各自考虑地基土实际基础形状的地基临界荷载,二者相比即得相应的形状修正系数;确定其与基础宽长比B/L的拟合关系,进而得到考虑应力状态的形状修正地基承载力近似公式,方便工程应用。
The foundation soil is divided into two types ： c-type soil and φ-type soil. Calculation program of critical load and approximate formula of depth modified critical load that took soil＇ s base shape in considered are used to calculate shape modified coefficients, and a relation fitting of the coefficients and weith height ratio of base B/L are determined. Therefore, a shape modified formula of critical load which can take actual stress state of subsoil into account is obtained.
