自重湿陷性黄土地基渡槽优化设计OA

The Nanwu Ferry is located on the loess plateau in Beizhao Irrigation District,Shanxi Prov-ince.The terrain is strongly cutina"V"shape and is characterized by strong collapsible loess,with slopes prone to collapse.Based on the characteristics of the terrain and geological conditions,a superior arch type aqueduct+cast-in-place pile foundation structure was selected through comparative analy-sis.By using structural statics methods to determine structural dimensions,and then using MIDAS fi-nite element software for static and dynamic simulation analysis,the two methods are mutually verified,resulting in higher safety and reliability in structural design.Preplanning the structural dimensions can improve the computational efficiency of pre-processing and analysis while ensuring the accuracy of finite element calculations.This design method provides reference significance for similar aqueduct engineer-ing designs.
