摘要
阐述了结构优化设计的基本原理和步骤;以双排桩工程造价为目标函数,以位移及抗弯强度等为约束条件,建立了双排桩支护结构的优化设计数学模型;通过编程计算,实现了此类结构的优化设计。算例分析表明,该优化设计方法经济效益显著,可供此类工程设计中参考应用。
This paper explains the foundamental principle and steps of structural optimal design.Considering the total cost of double-line pile as object function, and taking its flexural capacity and displacement as constraints,the mathematical model of double-line pile structural optimum design is established.By compiling program and calculation,such type of structural optimum design is carried out.A typical example shows that the optimnm design method can bring about tremendous economic benefit so that it can be widely applied in practice.
