摘要:
从结构工程角度研究并探索了减少高速铁路桥梁振动的技术和措施,包括:运用预应力技术,作好桥梁的微挠度控制; 搞好PC箱梁预应力设计,解决PC箱梁的斜裂缝和挠度难题; 采用体外预应力提高桥梁结构刚度; 采用碳纤维增强塑料(CFRP)外包技术,加强桥墩柱抗震能力; 探索智能预应力理论及其在桥梁中的应用。此外,提出了采用加气轻质混凝土(ALC)板建造声屏障以消除噪声的建议,介绍了采用新型材料CFRP索建造混凝土斜拉桥的创新研究和工程实践。
Abstract:
Author researched and explored the techniques and measures to reduce vibration of high-speed train bridges from the viewpoint of structure engineering, such as applying prestressing techniques to control micro deflection of bridges; doing well design of PC box beam to resolve skew cracking and deflection problems; adopting external prestressing techniques to improve structure stiffness of bridges; adopting outside wrapping CFRP column techniques to enhance aseismatic ability of piers; exploring the theories of intelligent prestressing theory in bridge structures. Moreover, author also put forward using ALC slabs to build noise barrier in order to eliminate noise. Finally, innovation research and engineering practice of a concrete cable-stayed bridge with CFRP cables were briefly introduced.
