摘要
渡江战役纪念馆主体建筑造型像战舰,结构受力体系复杂。船头部位以4榀三角形钢筋混凝土悬挑桁架梁为主支撑结构体系,托起船头部位次梁、板,形成超长、超重悬臂结构。依据结构体系受力特点,在保证结构体系安全稳定性的前提下,合理划分了悬臂结构各施工工况,同时采用型钢与钢管组合高大模板支撑体系。通过项目实施过程中开展的施工监测研究分析,验证了技术方案的可靠性,确保了结构的安全性。
The main building of Changjiang-crossing Campaign Memorial looks like a warship. Four triangle reinforced concrete cantilever beams are designed as main supports of the bow to bear weight from secondary beams and boards,thus a super-long and overweight cantilever structure is built up. According to bearing characteristics,construction conditions of the cantilever structure are rationally defined under premise of keeping safety and stability of the system. At the same time,composition of section steel and steel pipes is used for large and high formwork. Monitoring results during construction process indicates that the technical scheme is reasonable and the structure is safe.
