通过建立有限差分法计算大体积混凝土温度场的模型;以西安市某高层住宅楼的筏板大体积混凝土基础为背景,分析筏板大体积混凝土基础原材料优选、配合比确定、温度场求解等方面问题;并从温控指标的确定、混凝土入模温度控制、施工方案的选择、温度监测方案等方面对该工程筏板大体积混凝土基础的温控措施进行研究。
Based on the mass concrete of raft foundation of a high-rise building in a community in Xi' an, it is analyzed the optimization of raw material, confirmation of mix proportion, questions on the aspects of solving the mass concrete of raft foundation' s thermal field by finite difference mothod. It is researched that thermal control measures of the mass concrete of raft foundation of this project by confirmation of thermal control index, thermal control on the pouring of concrete, selection of construction scheme, temperature monitoring.
