摘　　要：水闸地基屈服范围的计算目前大都是采用规范建议的查表方式来进行。这种传统的简化方法不能完全表征地基受力特性,且不利于进行高效参数化设计。鉴于此,笔者借助VBA调用ANSYS结合莫尔库仑法进行地基应力场计算,再在VBA中自动绘制地基粘结力等值线图,确定地基屈服范围,同时分析了土体粘结力和内摩擦角对地基屈服范围的直接影响。Currently it is mostly adopted specification recommended way of look-up table to carry out the calculation of yield scope of sluice foundation. The traditional simplified method can not fully express the foundation mechanical characteristics, or conducive to efficient parametric analysis. According to this, the author uses VBA invoking ANSYS to take the calculation of the stress of foundation combined with Mohr coulomb＇ s law. Then it draws foundation bond contour map to determine yield scope of sluice foundation. At the same time, it analyzes the direct affection of the cohesive force and internal friction an- gle to the yield scope of sluice foundation.
