摘要
疏港公路在海底抛石施工中,由于海面风力强、潮汐的影响大,施工和测控难度相对较高.为了适应海上疏港公路抛石施工的需要,基于DTM建模技术自主研发了海底抛石施工计算机辅助系统,用Visual Studio 2005编程实现了海底地形云图显示、抛石工程量计算和动态水深预警等相关关键技术.在此基础上,系统研究了疏港公路海底抛石施工的工艺原理、流程和具体操作要点.研究结果表明:海底地形云图和动态水深预警可以直观反映海底地形情况,为施工组织和进度安排提供指导;根据潮水特点和不同船只安全航行水深,利用开体驳、平板驳等多种船只协同施工配合抛石,可以有效避免船只搁浅;采用陆抛进占法和大侧小中抛石法进行抛石施工,可确保抛石的准确性和密实性.
The construction process of submarine riprap is difficult to control because it＇s highly affected by the strong sea wind and tidal. In order to adapt the need of submarine riprap construction, SRC-CAD is developed on the basis of DTM modeling technology. The related key technology like the nephogram display of submarine terrain, quantity calculation of riprap and dynamic depth warning is programmed with Visual Studio 2005. The principle, process and operation points of submarine riprap construction are also discussed. The results indicate that nephogram of submarine terrain and dynamic depth warning can intuitively reflect submarine terrain condition which provides guidance to construction organizing and scheduling. Using the method of combining bottom-dump barge with tablet barge in riprap construction can effectively avoid vessels stranded to take tidal characteristics and safe sailing depth of different vessels into consideration. In addition, the accuracy and consistency are ensured with riprap method of land cast capture and big out and small in.
