Research on Design and Construction Reliability of Cast-in-place Support of Yingxi River Extra-large Bridge
Aiming at the process of construction scheme design and demonstration of Yingxi River extra-large bridge in extremely special construction environment,this paper uses Midas Civil finite element software to establish the overall numerical model of the support,and analyz-es the changes of internal force,displacement and other influencing factors of the support.The results show that the strength,stiffness and stability of the support meet the stress requirements,which is in good agreement with the actual engineering conclusion.At the same time,in view of the challenges and problems faced by the support structure design and construction process of the cast-in-place sup-port under the special environments of being adjacent to the railway operating line and overcrossing railway under construction,the corresponding solutions are proposed.
