The Application of GPS RTD System in the Diversion Channel Closure and the Third-stage Soil Rock Cofferdam Building Engineering in Three Gorges Projection

本文介绍了RTD实时动态GPS测量系统在三峡导流明渠截流及三期土石围堰工程中的应用情况。主要用于水下地形测绘和明渠下游合金网石兜抛投的动态导航定位。将GPS技术应用于大型施工项目 ,能极大提高生产效率 ,创造出更好的经济效益和社会效益。GPS定位技术总的趋势是向高精度、实时性、自动化、和可靠性方向发展 ,随着它的广泛应用 ,测绘技术也将会发生深远的变革。

The application of GPS RTD system is introduced in the diversion channel closure and the third-stage soil rock cofferdam building engineering in Three Gorges projection. The system is mainly used in underwater topographical surveying and dynamic positioning of underwater riprap. It can raise production efficiency and creating better economic effect and society effect that GPS is applied in large construction projection. GPS is developing to high precision, real time, automation and reliability. With its widely application, surveying technique will generate far-reaching change.
