交通事业的发展使桥梁建设向技术强国迈进。现在,各种大型桥梁已经成为我国交通网络的重要枢纽。在桥梁建设中,测绘是首要任务,为了能够保证桥梁质量必须使测量数据精准、真实。我国地域条件复杂,跨江、跨海大桥地质条件多样,对施工精度和施工工艺都有一定的要求,随着桥梁越来越多,传统的测量手段已经难以满足建设的需要。应当引进GPS技术,应用于桥梁设计阶段的数据采集,施工过程及运营阶段的实时监测,获取更加精确和完整的信息,为桥梁的顺利建造提供技术保障。
The development of transportation causes the bridge construction to move forward to a technological power. Now, all kinds of large-scale bridges have become an important hub of China’s transportation network. In the bridge construction, mapping is the primary task, in order to ensure the quality of the bridge must make the measurement data accurate and real. Due to the complex geographical conditions in our country, the geological conditions across the river and across the sea are diverse. Both the construction accuracy and the construction technology have certain requirements. As the number of bridges increases, the traditional measurement methods can hardly meet the needs of construction. GPS technology should be introduced and applied to the real-time monitoring of data collection, construction process and operation phase of the bridge design stage to obtain more accurate and complete information so as to provide technical support for the smooth construction of the bridge.
