摘　　要：温度应力耦合问题是大体积混凝土工程施工期的核心关注点,大量相关的计算软件对用户能力要求较高,难以实现普遍性应用。本文以Excel软件为基础,配合VBA编程,实现了前处理的直观化,并通过C语言编制后台程序,利用Marc为核心求解器,完成了大体积混凝土温度应力耦合仿真计算系统的开发.该系统的用户友好性较强,直观易懂,能够实现前处理,计算、后处理全套过程的自动化,进一步提高了大体积混凝土工程仿真计算分析的通用性。通过国内某大型混凝土拱坝的实际算例,证明了该套系统的正确性和可行性.The thermal stress coupling problem is the key issue during the construction of mass concrete.Plenty of commercial FEM software products are not widely applied because they have high capability requirements of the users.In the paper,based on Excel and VBA programming,the user-friendly preliminary treatment is realized.With the background program compiled by C language as well as the core solver of Marc,simulation platform of thermal stress coupling of mass concrete is developed.The user-friendly platform can achieve an automated procedure of preprocessing,calculating and post-processing and improve the generality of simulation calculation of mass concrete projects.In addition,the practical calculation case of domestic concrete project provided in the paper proved validity and practicability of the platform.
