沪杭客专海杭特大桥上承式拱桥转体施工关键技术研究

Key Technology of Rotation Construction of a Deck Arch Bridge with Spans of Hai-Hang Large Bridge in Hu-Hang Passenger Dedicated line

对沪杭客专海杭特大桥上跨石大公路88m+160m+88m自锚上承式拱桥的转体施工关键技术进行研究。通过对桥梁进行称重、试转试验,验证了转体系统的可靠性,为正式转体提供了科学依据。并对转体系统关键构造及工序提出了改进措施,保证了该桥顺利施工。

The key technology of rotation construction of a self-anchored deck arch bridge with spans （88＋160＋88）m of Hai-Hang large bridge in Hu-Hang passenger dedicated line has been researched. Throng weighting and trial rotation for the bridge,the reliability of the rotational system is verified, and it can give detailed scientific basis for the formal rotation construction.Also,the novel and ad-vanced improved measures are proposed for the key structure and procedure in the rotational system of this bridge,ensuring the successful implementation of the bridge.
