摘要:
短线匹配法节段预制拼装梁施工线形控制贯穿整个桥梁施工过程,预制阶段线形控制为重点,但线形控制的依据是测量数据,测量数据难免产生人为误差,预制阶段的测量误差在拼装阶段才会反应出来,因此拼装阶段误差调整的措施也必不可少。以洞头峡跨海大桥引桥节段梁架设施工为依托,介绍短线匹配法节段梁拼装阶段线形控制的方法以及误差调整的措施。

The linear control of segment prefabrication and assembly construction using the short linematching method runs through the entire construction process,with the focus on linear control during theprefabrication stage. However, the basis of linear control is measurement data,which inevitably leads tohuman errors. The measurement errors during the prefabrication stage will only be reflected in theassembly stage. Therefore, measures for adjusting errors during the assembly stage are also essential.This article takes the construction of the section beam erection of the Dongtouxia Cross Sea Bridge as abasis to introduce the method of linear control and error adjustment measures during the section beamassembly stage using short line matching method.
