Abstract
Taking the demolition and reconstruction of the Taisu Canal 1#Aqueduct in Hualiangting Irrigation District as an engineering case,Midas civil finite element software was used to model and analyze the stress and deformation of the aqueduct structure under different working conditions,identify the key section of the main arch ring,extract internal forces for reinforcement and bearing capacity verification.The calculation results indicate that the design water depth condition(basic combination)is the most unfavorable condition,and the key stress sections for controlling structural design are the arch crown,arch foot,1/4,and 3/8 sections.Using Midas civil finite element software combined with hydraulic specifications to set the basic parameters built-in in the program can be used for the calculation of aqueduct structures,providing reference for similar engineering calculations and designs.关键词
