摘要
溢流表孔作为拱坝重要的泄水建筑物,对大坝安全运行具有重要的作用.以某拱坝溢流表孔为例,该表孔地处高纬度严寒地区、结构复杂且地震烈度高,通过三维有限元法对表孔在不同工况下的静、动力应力进行计算分析,根据计算结果,对表孔结构进行配筋设计,确定受拉钢筋的布置方式及配筋量,使表孔结构钢筋布置满足承载力及正常使用要求.研究结果可为类似工程配筋设计提供参考依据.
Abstract
As an important sluice structure of arch dam,the overflow crest outlet plays an important role in the safe operation of the dam.Taking the overflow crest outlet of an arch dam as an example,the crest outlet is located in the high latitude cold area,the structure is complex and the seismic intensity is high.The static and dynamic stresses of the crest outlet under different working conditions are calculated and analyzed by the three-dimensional finite element method.According to the calculation results,the reinforcement design of the crest outlet structure is carried out to determine the arrangement and reinforcement amount of the tensile reinforcement,so that the reinforcement arrangement of the crest outlet structure can meet the bearing capacity and normal use requirements.The research results can provide reference for the reinforcement design of similar projects.
