纤维编织网增强自应力混凝土压力管道数值模拟研究

Numerical Simulation of Self Stressing Concrete Penstock Reinforced by Fiber Woven Mesh

混凝土钢衬管道是水电站引水系统的常用输水管道类型,防止其混凝土大面积开裂是此类管道设计的重要要求。以某水电站的引水压力管道为例,利用数值模拟计算的方法,对纤维编织网增强自应力混凝土钢衬压力管道开裂性能进行研究,并根据研究结果提出具体的工程建议。

The concrete steel lined pipeline is a common type of water delivery pipeline in the water diversion system of hydropower station.It is an important requirement for the design of this kind of pipeline to prevent the concrete from cracking in a large area.Taking the diversion penstock of a hydropower station as an example,this paper studies the cracking performance of the steel lined penstock reinforced by fiber woven mesh by numerical simulation,and puts forward specific engineering suggestions according to the research results.
