引滦入唐工程某渡槽裂缝成因及对策分析

Crack Analysis and Countermeasures on an Aqueduct in the Water Diversion Project from the Luanhe River to Tangshan City

针对引滦入唐工程中某渡槽的开裂情况,从渡槽的两个使用状态入手进行分析,考虑按旧规范计算对设计造成的误差,采用大型有限元分析程序分析了渡槽各种工况的运行情况,并根据使用情况分析了开裂原因,提出了加固意见和同类渡槽设计的建议。

Aiming at the crack situation of an aqueduct of the water diversion project, we carry on the analysis from two running states of the flume, considering the error which is produced by the internal force calculation according to the old standard, uses a large-scale finite element analysis to analyze the running states, and analyzes the reason of the crack forming based on the using condition, and brings forward the reinforcement opinion and design suggestion about the similar flume.
