摘　　要：　基坑工程涉及土压力计算、内力位移计算、整体稳定性验算、降水计算以及配筋等多方面的问题,尤其是如何确切地确定土压力的分布及大小,求最大内力值确保基坑稳定。悬臂式支护结构设计计算软件计算土压力采用经典法和弹性支点法两种计算模式(三角形和矩形)。通过该设计计算软件对工程实例计算,发现弹性支点法与经典法中按矩形分布计算结果相近,而与经典法中三角形分布计算结果相差较大,随着开挖深度的增加相差增大,并且经典法计算结果偏于保守。foundation pit engineering includes the calculation of earth pressure,internal force and displacement,dewatering,reinforcement and examination of stability,especially the calculation of earth pressure.The design count software for cantilever supporting structrue uses the classical and traditional method(triangle distribution and rectangle distribution)and the finite element method.By the design count software,we have found out that the count results of finite element method are close to the count results of rectangle distribution and a great deal of difference to the count results of triangle distribution,and the count results of classical and traditional method are always greater than the count results of finite element method.
