Control technology of construction quality for high filled airport based on Beidou satellite navigation system

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.
