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 is divided into c-type soil foundation and φ-type soil foundation. By using the critical load calculation program considering the stress state of foundation soil and the approximate formula of critical load for depth correction considering the stress state of foundation soil, And the critical load of the foundation, the corresponding shape correction coefficient is obtained. The fitting relation between the ratio and the basic width-length ratio B / L is determined, then the approximate formula of the bearing capacity of the shape-amended foundation considering the stress state is obtained, which is convenient for engineering application.
