斜拉桥塔柱水化热温度应力分析

摘要

Using the heat conduction finite element method,the three-dimensional model was built with ANSYS to analyze coupled thermal stress,and temperature distribution characteristics as well as thermal stress developing laws were obtained,which got the theoretical basis and measures for pre-venting cracking.%根据热传导有限单元法原理，采用热-应力耦合的方法对混凝土浇筑水化热引起的斜拉桥空心塔柱的温度效应进行分析，运用 ANSYS 进行仿真分析，得到温度场分布特点以及温度应力的发展规律，为控制施工中的水化热温度裂缝提供了理论依据以及防止开裂措施。
