摘　　要：根据某高层建筑塔楼劲性柱实际尺寸,模拟浇筑两组C70高强高性能钢筋混凝土足尺柱,以检验混凝土配合比、工作性能及强度等参数是否满足实际施工要求;同时通过预埋传感器的方法对模拟混凝土柱进行了温度和变形的实时监测,为进一步研究C70高强混凝土在实际工程条件下的热学性能和变形性能提供技术依据。Based on actual sizes of soft type rigid column for a high-rise building tower, full-scale column for two groups of C70 high strength high proformance reinforced concrete is poured in order to test whether its working perfor- mance, mix proportion and strength can meet the requirements of constructions in the project. Meanwhile, real-time mini- toring of concrete column for temperature and deformation is carried out by embedded sensors, which can obtain technical basis for the further study on thermal properties and mechanical properties of C70 high strength concrete in practical engi- neering conditions.
