摘要: 山区机场高填方质量监控主要针对干密度进行监控,传统的监控手段均属事后检测、操作上以点代面,需要加强施工质量过程监控并对其进行快速监测。针对山区机场高填方质量监控的要求,在建立冲击碾压质量实时监测指标和要求的基础上,采用北斗卫星导航定位和3G无线传输技术,提出了机场高填方冲击碾压质量实时监控方法,以及冲击碾压过程的信息实时采集传输技术和GIS平台的冲击碾压过程可视化等主要技术,实现了冲击碾压轨迹、速度和遍数等施工信息的全过程实时监测。施工现场的初步试验表明,该技术能有效应用于山区机场,对提高机场高填方施工质量具有重要意义。Abstract: The quality control for the embankment of airport in mountain areas at present is mainly based on the control of dry density of soils. The traditional control methods estimate the construction quality of the entire area by monitoring a limited number of representative points, which is difficult to ensure the rolling quality effectively or to monitor the real-time compaction quality. According to the characteristics of high embankment quality control for mountainous airports, real-time monitoring indices and criteria are established. Using the Beidou satellite navigation system and 3G wireless transmission technology, the real-time monitoring method of impact rolling for high embankment of airport is proposed. Combining the real-time collecting technology and visualization technology, the real-time monitoring of the whole process about track, speed and number of compaction is realized. The tests at the construction site show that this technology can be effectively applied for mountainous airports in cost control, project management and quality monitoring, which is significant for improving the construction quality of high embankment of airport.
