摘要
本文提出了一套在总体上控制造价的复合地基及基础的优化算法 ,推导出考虑下卧层及沉降的复合地基及基础的优化设计数学模型 ,编制了求优化解的罚函数和复合形法程序 ,有效的解决了现行规范在使用过程中难以综合考虑下卧层强度、沉降及造价因素的问题。运用于实际工程取得了较好的经济效益 ,同时分析了不同设计参数的取值对总造价的影响 。
The paper proposes a kind of optimum algorithm to calculate the optimal solution to design the strip flooring on the composites foundations.The optimal mathemat ical model of determining suitable design parameters is derived,the program of o ptimum algorithm is compiled.The problem that it is difficult to employ the curr ent standard to design foundation on condition of the foundation settlement,the production cost is solved effectively.The variable design parameters are studied to control the production cost,the design suggestion is proposed at last. \[
