泥石流防治工程优化设计方法初探

STUDY ON THE OPTIMIZATION DESIGN FOR DEBRIS FLOW FROTFCTION ENGINEERING

本文介绍一种以可靠性理论为指导的泥石流防治工程优化设计方法。文中首先提出了由于泥石流荷载的不确定性而以概率约束表示的泥石流防治工程参数优化设计的模型；然后建立了用离散变量优化与随机模拟相结合的一种求解方法；最后应用实例对该方法的原理和计算程序进行了说明。

This paper investigates the optimization method for debris flow protection engineering design under the direction of the theory of reliability. First, an optimization model for the parameters of debris flow engineering is presented, which has the probability constraint due to the uncertainty of debris flow load. Then, a calculus combining the optimization of discrete variable with the stochastic simulation is established. Finally, the principle of the calculus and its calculating process are illustrated by a spetific example.
