摘要基于库仑理论的平面滑裂面假设，采用斜向条分法推导考虑滑裂面上填土的黏聚力、墙土间黏着力、均布超载条件下的黏性土主被动土压力合力及其作用点位置、土压力强度计算式，并给出临界破裂角的显式解答。分析结果表明：斜向条分法有效验证库仑理论假设土压力强度沿墙高线性分布的合理性，且现行经典朗肯和库仑土压力理论计算式皆为该公式在相应简化条件下的特例，对应用条分法计算土压力做了重要补充。

Abstract：Based on the sliding plane hypothesis of Coulomb earth pressure theory，diagonal slice method is used to deduce the formula of active and passive earth pressures，application position of resultant force and formula of earth pressure which considers the cohesion on sliding plane，the adhesive force on interface of soil and retaining wall，the uniformly distributed load，the critical rupture angle of explicit solution are also deduced. The formula effectively proves the Coulomb theory which assumes the earth pressure behind retaining wall is in linear distribution，besides the prevailing classical Rankine and Coulomb earth pressure formulas are two special examples of the formula that are simplified under the condition of relevant assumptions，which is an important supplement for the application of this method.

Key words： soil mechanics retaining wall earth pressure sliding plane Coulomb theory diagonal slice method linear distribution
