| Abstract: | n this paper comparative design of various culvert schemes and analysis of internal forces have been carried out by using plane and bar system finite element methed for different back-fill soils and filling heights in combination with the construction of adverse siphon through the Jialu River in the Zhaokou irgation district,Henan Province. The distribution of soil pressure around the wall,structural computation and optimum parameters are presented,which can be used for reference by designing departments. |
