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临界荷载近似计算公式,得出各自考虑地基土实际应力状态的地基临界荷载,二者相比即得相应的深度修正系数d_c,d_q,d_γ;分析了深度修正系数d_c,d_q对地基承载力的影响规律,给出了d_c,d_q的拟合公式,综合得出了考虑地基土实际应力状态的c-φ型土地基经深度修正后的承载力计算公式.
The foundation soil is divided into two types ： c-type soil and φ-type soil. Calculation program of critical load and an approximate formula of critical load that take soil＇s stress state into consideration are used to calculate depth modified coefficients dc, dq ,dy; influence of depth modified coefficients on bearing capacity of subsoil are analyzed. Fitting formulas of depth modified coefficients are given. Therefore, a depth modified formula of critical load which can take actual stress state of c-φ type subsoil into account is obtained
