Abstract
In order to study the mechanical properties of drainage pipe socket,a pipe-soil-fluid coupling numerical model was constructed by using ABAQUS software and Fluent software to study the effects of different flow rates,buried depth and load position on the mechanical properties of drainage pipe socket.The results show that the model can accurately reflect the mechanical behavior of pipe socket under load,and the error between the measured data and the simulated results is in the range of 4%～12%.The influence of flow velocity on the overall stress of the socket is limited,and it only changes weakly in the local area.When the loading position moves from-1.2 m to 1.2 m,the top stress of the socket tube ranges from 1.18 MPa to 1.50 MPa,and the top stress of the socket tube ranges from 0.02 MPa to 0.35 MPa.When the buried depth of the pipe increases to 1.0 m,the stress at the top and bottom of the pipe socket increases by 6.89%and 4.19%,respectively,compared with that at the buried depth of 0.8 m,and the stress at the top and bottom of the pipe socket increases by 24.31%and 35.40%,respectively,indicating that optimizing the loading position and rationally adjusting the buried depth can effectively improve the mechanical performance of the pipe socket.关键词
