摘 要:渡槽是引水发电、城镇供水和灌溉等输水过程中跨越山谷洼地等常见的交叉输水建筑物。为精确反映渡槽的承载能力特点,采用三维有限元法对渡槽进行结构分析,研究其应力分布特性,以我国西南地区某大型渡槽工程为例,基于有效控制断面的有限元应力成果进行配筋设计,裂缝宽度可满足规范要求,成果可靠。The aqueduct is a common water diversion structure to cross the valley or depression areas in diversion-type hydropower stations,water supply or irrigation projects. Based on a large-scale aqueduct project in Southwest China,a structural analysis is carried out to study the stress distribution and accurate carrying capacity characteristics of the aqueduct with the three dimensional finite element method. Structural reinforcement design is then conducted based on the stress distribution results of the effective control sections. The results show that the requirement on the crack width is satisfied and the design is reliable.
