一、前言 考虑钢管与外国钢筋混凝土联合受力的下游坝面压力管道的结构优化设计,主要包括:(1)经济直径的优化:(2)钢管壁厚及环形钢筋配筋量的优化,在满足设计规范或设计准则的前提下,实现这两方面的优化,就意味着减少钢材用量,提高发电能力,从而获得显著的经济效益。
I. INTRODUCTION The structural optimization design of the downstream dam surface pressure pipe under the joint force of steel pipe and foreign reinforced concrete is mainly considered as follows: (1) Optimization of economic diameter: (2) Optimization of pipe wall thickness and reinforcement of annular steel bar, To meet the design norms or design guidelines under the premise of achieving these two aspects of optimization, it means reducing the amount of steel, improve power generation capacity, resulting in significant economic benefits.
