摘要

针对古沉船整体打捞工程,利用分布式光纤传感技术替代常规的变形监测手段,在“端板-纵梁”框架整体下放过程中对纵梁和端板进行变形监测.监测结果表明:“端板-纵梁”下放全过程中,端板的变形控制在1.5 mm内,变形量可以忽略;受定位桩与“端板-纵梁”间摩擦力的影响,纵梁最大变形量为50 mm;对定位桩打磨切割可有效减小纵梁变形量,纵梁最终变形量约为35 mm.

Abstract

For the integral salvage project of ancient sunken ships, the distributed optical fiber sensing technology is used instead of conventional deformation monitoring methods to monitor the deformation of the longitudinal beam and end plate during the overall lowering process of the “end plate longitudinal beam” frame. The monitoring results show that during the entire process of lowering the “end plate longitudinal beam”, the deformation of the end plate is controlled within 1.5 mm, and the deformation amount can be ignored. Due to the friction between the positioning pile and the “end plate longitudinal beam”, the maximum deformation of the longitudinal beam is 50 mm. Grinding and cutting the positioning pile can effectively reduce the deformation of the longitudinal beam, and the final deformation of the longitudinal beam is about 35 mm.

Key words： wreck; optical fiber monitoring; integral salvage; deformation monitoring
