Abstract: |
The self anchored suspension bridge on Jiancai North Road in Xi’an city is a typical cable structure. According to the force transmission characteristics of the cable, the main tower bearing platform is planned to adopt the construction method of laying embedded parts in the bottom layer and pouring the upper layer at one time, which is very different from the traditional layered and phased pouring of the bearing platform. In this paper, the finite element analysis software is used to carry out the fine modeling analysis of the foundation cap and its foundation temperature diffusion area, and the actual simulation of temperature and stress is carried out, and the “temperature stress asynchronous” effect caused by the bottom layer embedded parts and the upper layer pouring construction is studied; by analyzing the asynchronous difference of stress and temperature peak, the transfer law of temperature core area and the temperature field change caused by surface temperature control effect, the construction and monitoring measurement scheme is optimized. |
