| 摘 要： | 大体积混凝土在现代的土木工程施工中已非常普遍,但常常出现裂缝和变形,严重影响了结构的整体性和耐久性。本文通过利用结构有限元分析程序MIDAS/Civil对一座待建桥梁承台进行水化热分析研究,总结了承台混凝土在水化热影响下温度的分布规律以及温度随时间的变化规律,同时提出了防止混凝土开裂的一些应对措施。

| Abstract: | The massive concrete has been widely used in modern civil engineering,but it often has the problems of crack and deformation,which infuenced the entirety and durability of the whole structure seriously.In this paper,a hydration heat analysis of the platform of a cable stayed bridge is carried out by using MIDAS/Civil structure finite element method analysis program,the analysis summarizes the temperature distribution regulation of platform concrete influenced by hydration heat and the temperature changing regulation effected by time,meanwhile,some countermeasures of preventing the crack of concrete are put forward. |
