摘　　要：基于莫尔—库仑强度理论,重新推导了K0≠1条件下的地基临界荷载计算公式,该公式避免了人为的过高估计地基承载力的缺陷,能够更好的反映地基承载力的实质。通过实例计算,对新旧承载力公式的计算结果进行了比较。Based on the Mohr-Coulomb strength theory,a new formula of critical load of subsoil with K0≠1 is deduced.This method avoids artificial overestimated results due to the assumed K0≠1,which can reflect the essentials of subgrade bearing capacity more accurately.Example calculations indicate that the new formula is more reliable than the old formula.

关 键 词：地基承载力 临塑荷载 临界荷载 莫尔—库伦破坏准则 静止侧压力系数
