摘要
基于深圳某下沉式LNG储罐基坑及相关地下结构工程,通过实测温度数据和数值模拟结果分析了不同浇筑方式和不同养护条件等因素对大体积混凝土温度、应力的影响及其变化规律,并分析了对工程最高温度、最大温升等规范要求参数的影响,验证了该基坑底板工程的大体积混凝土温度控制方法的有效性。
Based on the foundation pit of a sinking LNG storage tank and related underground structure project in Shenzhen,the influence of different pouring methods and curing conditions on the temperature and stress of mass concrete and their variation laws are analyzed through the measured temperature data and numerical simulation results,and the influence on the parameters required by the specifications such as the maximum temperature and maximum temperature rise of the project is also analyzed.The effectiveness of the temperature control method for the mass concrete of the foundation pit bottom plate project is verified.
