摘　　要：通过采用单梁法和梁格法对异形箱梁的计算分析,对异形箱梁设计过程中的问题进行了探讨,同时提出异形箱梁的设计方法以及设计中应该注意的地方。证明梁格分析法在异形箱梁设计中简单可行,分析的精度可达到一般工程设计的要求。By way of calculative analysis of heteromorphic box beam by single girder method and gridiron method,the paper makes an approach to problems in design process of heteromophic box girder, at the same time puts forward the design methods for heteromorphic box girder as well as the points for attention in design. Practice proves that gridiron analysis methods are simple and feasible in design of heteromorphic box girder,its analytie accuracy might attain the requirements for design of ordinary engineering.
