| 实际挡墙坡面多为异形，但目前异形坡面主动土压力的计算方法不便于日常使用。基于库仑土压力理论平面滑动假设，结合图解法适用范围广、数解法计算精度高的优点，建立了利用CAD和Excel软件求解异形坡面主动土压力的简便计算方法。采用不同类型坡面和附加荷载的组合对计算方法进行验证，结果显示计算方法与文献方法、规范公式计算结果相近，证明了计算方法的合理性、正确性和较强的适用性；相较于其他方法，计算方法可求解黏性土异形坡面的主动土压力，计算过程简单易学，计算结果精度较高，在工程实践中具有较好的实用和推广价值。 |

| The actual retaining wall slope surfaces is mostly irregular，but the current calculation method for active earth pressure on special-shaped slope surfaces is not convenient for daily useBased on the Coulomb’s earth pressure theory and the plane sliding assumption，combined with the advantages of the graphical construction with wide applicability and the numerical method with high calculation accuracy，a simple calculation method for solving the active earth pressure on special-shaped slope surfaces by using CAD and Excel software is establishedThe combination of different types of slope surfaces and additional loads is used to verify the calculation methodThe results show that the calculation method is similar to the literature method and the standard formula calculation results，which proves the rationality，correctness，and strong applicability of the calculation methodCompared with other methods，the calculation method can solve the active earth pressure on cohesive soil special-shaped slope surfaces，with simple calculation process，high calculation accuracy，and good practical and promotional value in engineering practice |
