Some results are as follows under the action of vertical load , piles and soils are able to support upper loads , this improving the bear capacity of composite foundation a lot ; changing the character of the pile during transferring the vertical stress , reducing compressive stress under foundation 在垂直荷载作用下,桩、土都可以承担上部荷载作用,进而能大幅度提高复合地基承载力,改变了桩传递轴向应力的特征,减小了基础底面的压力等。
Abstract : optimum design of individual foundation considering the effect of strength and deformation is discussed in this paper . the optimal mathematical model of determining the bottom surface demention of individual foundation under eccentric load is derived . the optimal solution is decided by method of optimization and the method we select is penalty fonction and complex method . the program of optimum algorithm is comiled and design and drawing of individual foundation is completed . the final results of engineering samples suggest that the cost of material and engineering amount can reduce approximatly 5 % - 6 % . a fair - sized economic efficiency can be received by using optimum method to design foundation 文摘:笔者讨论了独立基础在考虑强度和变形条件下的优化设计.导出了确定独立基础底面尺寸的优化数学模型,导出了偏心荷载作用下基础的高度和底面配筋的计算公式,求解优化解采用最优化方法的复合形法和罚函数法.通过基础实例和工程实例的计算表明优化设计可以节省材料和工程量5 16 .所以将本文优化方法用于基础设计,会产生较大的经济效益
