混凝土渡槽的病害与加固及其动力学研究

RESEARCH PROGRESS OF CONCRETE AQUEDUCT DISEASES AND REINFORCEMENT AND ITS DYNAMICS

渡槽作为一种重要的水工建筑物,在我国有着广泛应用。针对这种特定的结构,分析了其在不利工作环境和设计施工条件下的病害及其对应的加固改造措施。同时梳理了渡槽的动力学研究进展,指出了流固耦合和桩–土相互作用因素对渡槽动力特性和地震作用响应的影响。论述了渡槽的减隔震技术,分析了不同减隔震措施的减隔震效果,从而为其抗震研究和减隔震设计提供依据。

Aqueducts,as an important hydraulic structure,are widely used in China.For this specific structure,the diseases and corresponding reinforcement and transformation measures under unfavorable working environment and design and construction conditions were analyzed.At the same time,the dynamic research progress of the aqueduct was reviewed,and the effects of fluid solid coupling and pile soil interaction factors on the dynamic characteristics and seismic response of the aqueduct were pointed out.Discussed the seismic reduction and isolation technology of aqueducts,and analyzed the seismic reduction and isolation effects of different seismic reduction and isolation measures.Thus providing a basis for its seismic research and seismic isolation design.
