摘　　要：计算坐落在可压缩层或持力层深度有限的弹性基础上的框架结构,需考虑超静定结构和有限深地基的弹性关系,且在计算过程中需计入地基两侧对称或非对称的边荷载作用,计算时采用有限深弹性地基理论和超静定框架内力的计算方法,使计算模型更接近工程实践.It is necessary to consider the elastic relationship between the statically-inderterminate structure and the foundation with limited depth during the computation made on the frame structures located on the elastic foundation of compressible stratum or supporting stratum with limited depth, and then the side load actions of both the side symmetry or non-symmetry need to be taken into the computation. For the computing model being more close to the engineering practice, the theory of the elastic foundation with limited depth and the computation method for and the internal force of the statically-inderterminate frame have to be used as well.
