摘要 现阶段中国正在大力兴建山区机场以改善当地的交通条件,而通过"削山平谷"形成的山区高填方机场在建造和运营中还面临许多难题。针对山区高填方机场建造过程中施工质量难以控制的问题,利用"互联网+"系列技术开发了机场高填方压实质量实时监控系统,可实现对施工压实质量的全面控制和管理,并结合无人驾驶技术能够实现自动化智能建造;针对高填方施工完成后填筑体变形沉降的问题,建立了全生命周期的安全监测系统,可对长期变形进行预测,起到灾害预警作用;针对机场道面下土层含水量增加的锅盖效应现象,通过试验模拟验证了其内在机制,提出了在冻结锋面以下铺设隔气层的有效解决方案。 A large number of airports are under construction in mountainous areas in China, to improve the local traffic conditions.However, the construction and the management of the high filling airports, built by"cutting the mountains to fill the valleys", still face many difficulties. In order to control the quality of the high filling project, a real-time monitoring system for high filling compaction is developed by using the "Internet Plus" technology. The driverless technology makes the automated intelligent construction become a reality;In order to control the settlement after the construction, a safety monitoring system in the whole life cycle is established, which can predict the long-term deformation and issue disaster warnings in advance. In order to deal with the increased water content of the shallow soils under the airport runway, known as the pot effect, both laboratory and field experiments are conducted to trace the causes. Meanwhile, an effective engineering measure is proposed to reduce the pot effect by laying the insulating layer below the position where the soil temperature is around 0 ℃.
