摘要
梳理了公路边坡安全监控技术的发展和应用研究,从监测手段、监测内容、监测对象和技术设备4个方面进行综述,探讨了传统和智能化公路边坡安全监控技术存在的不足,并给出合理建议,预测了未来边坡监控技术的发展方向。分析表明:传统公路边坡安全监控技术,主要通过现场人员辅以基础仪器监测的技术设备对边坡地表位移变形进行监测,存在成本高、功耗大、精度低、不连续、易受干扰等不足;智能化公路边坡安全监控技术,以空、天、地、内的非接触式远程监测为主,通过智能化、自动化监测技术设备实现对边坡地表和边坡体内部位移和应力的动态、长期、连续监测,但目前技术理论结合度低、技术手段整合度低、多源信息融合度低;未来公路边坡安全监控技术,预测大致发展方向包括构建综合监测技术、实现风险能级转化、打破成本应用牵制、促进多源信息融合,并提出未来的研究方向包括物联网技术拓展、大数据挖掘、监测体系完善、多技术融合。
This paper combines the development and application research of highway slope safety monitoring technology,reviews four aspects of monitoring means,monitoring content,monitoring objects and technical equipment,discusses the shortcomings of traditional and intelligent highway slope safety monitoring technology,and gives reasonable suggestions,predicts the future development direction of slope monitoring technology.The analysis shows that the traditional highway slope safety monitoring technology mainly monitors the slope surface displacement and deformation by the field personnel supplemented by the technical equipment of basic instrument monitoring,which has the deficiencies of high cost,high power consumption,low accuracy,discontinuity and easy to be disturbed;the intelligent highway slope safety monitoring technology,mainly non-contact remote monitoring by air,sky,ground and inside,realizes dynamic,long-term and continuous monitoring of the slope surface and internal displacement and stress of slope body through intelligent and automatic monitoring technical equipment.But the presesnt technology is not highly combined with theory.The integration of technical means and multi-source information are low.The future road slope safety monitoring technology is predicted to develop in the general direction of building comprehensive monitoring technology,realizing risk energy level transformation,breaking cost application constraint and promoting multi-source information integration,and future research directions include The future research directions include expansion of Internet technology,big data mining,improvement of monitoring system,and integration of multiple technologies.
