超大面积混凝土地面结构无缝施工数值模拟研究

摘要

With the development of technology and society, scale of various kinds of architectures has been expanding, following which whole super large area concrete ground is widely applied. The importance of crack-free construction technology has been obtaining popular approval in preventing and con-trolling the cracking of super large area concrete ground structure. Based on practical cases, the crack-free construction technology of stress releasing in short distance is studied, the finite element software ABAQUS is applied to simulate and analyze the relation between concrete hydration water and tem-perature to finally explore the temperature conduction relation between adjacent concrete pouring blocks. It can offer some references for similar engi-neering.%随着科技的发展和社会的进步，各种建筑物的规模都在大幅度提升，随之产生的大面积混凝土整体地面在建筑工程中得到了广泛的应用。为了预防和控制大面积混凝土地面裂缝的出现，无缝施工技术得到了越来越广泛的认可。该文以实际工程为依托，对短距离释放应力无缝施工技术进行了研究，利用有限元软件ABAQUS模拟分析施工过程中混凝土水化热与温度的关系，探究相邻混凝土浇筑块的温度传导关系，以期能对类似工程无缝施工起到一定借鉴作用。
