船载水上水下一体化测量系统在跨海大桥中的应用——以胶州湾跨海大桥为例

Application of Shipborne underwater Integrated Measurement System in Cross-sea Bridge——Taking Jiaozhou Bay Cross-Sea Bridge as an Example

摘要:

船载水上水下一体化测量系统是近年来新发展的一项技术，依托船舶载体，集成多种高精度传感器，实现水上水下一体化快速三维测量。针对跨海大桥水上水下测绘中桥体高大复杂、桥下测量存在遮挡及海上作业条件差、难度大等问题，本文以胶州湾跨海大桥为例，介绍了VSursW船载水上水下一体化测量系统，成功实现了跨海大桥水上水下一体化无缝测量，并进行精度评定，完成水上水下成果整合，首次形成胶州湾跨海大桥完整水上水下三维数据，为船载水上水下一体化测量系统在实际中的应用提供了经典案例。

Abstract:

Shipborne underwater integrated measurement system is a new technology developed in recent years, which relies on the ship carrier and integrates a variety of high-precision sensors to realize the integrated three-dimensional measurement of water and underwater. In view of tall and complex bridge body, occlusion in underwater survey, poor working conditions at sea and difficulty in underwater survey, taking Jiaozhou Bay Bridge as an example, VSurs-W shipborne integrated underwater survey system has been introduced. Combinomg with actual situation, the integrated underwater underwater survey system of the bridge has been successfully realized, and the accuracy has been assessed. The integration of the above and below water results is completed, and the advantages and disadvantages of the system in practical application have been illustrated. It will provide a classic case and opens up ideas for further application of the ship-borne above and below water integrated measurement system in practice.
