摘　　要：根据普通混凝土构件正截面承载力的通用计算模型,本文建立了水下混凝土短柱正截面承载力计算的一般方法,得出的计算值与试验值吻合较好。根据现行普通混凝土结构设计规范,本文提出了水下混凝土短柱正截面承载力的简化计算公式,运用此公式计算出的结果与试验值吻合很好,说明此公式适用于水下混凝土短柱。最后得出现行普通混凝土规范给出的正截面承载力公式适用于水下混凝土。According to concrete member, a general the general calculation method for calculating model of normal section bearing capacity of normal normal section bearing capacity of non - dispersible underwater concrete short columns is established. Using the method, the calculated values are corresponding with experimental results quite well. Based on the existing normal concrete structure design code, a simplified calculation formula for normal section bearing capacity of underwater concrete short columns is obtained. Using this formula, the calculated results coincide with those of the tests very well. So it is applicable to the underwater concrete short column. And the normal section bearing capacity formula from existing normal concrete structure design code is also applicable to the underwater concrete.
