摘要
提出了一种确定过水围堰隧洞导流方案经济洞径的优化方法。即将导流费用函数作为目标函数,建立围堰高度和洞径间的函数关系,利用非线性规划的方法求出其经济洞径。同时还列出了方圆形、圆形和马蹄形三种常用断面的断面系数,为减少计算工作量提供了条件。
This paper presents a new method of searching economical diameter in diversion scheme of diversion tunnle combining with overtop cofferdam.It takes diversion-cost function as object function and seeks for function relation of cofferdam hight and diversion tynnle diameter with the application of theory of non-liner programming.It will decrease the calculation amount and simplify calculation course and improve calculation precison.
