GIS支持下的大型高边坡安全监测预警模型研究

Study on GIS-based high slope monitoring and prediction model

近年来在边坡工程变形预测和滑坡研究中,GIS作为一项新技术得到不断应用。目前大多数学者只是将GIS技术作为一个数据准备和处理的手段,采用统计分析方法来研究边坡破坏和各种影响因素之间的关系,将定量的力学分析模型和GIS技术结合来进行边坡稳定性研究较少。为提高边坡变形失稳和滑坡的安全评价的精度,提出了GIS支持下的高边坡工程安全监测滑坡预警模型,将GIS与边坡确定性分析模型结合,给出边坡稳定的安全判断,并以现场的位移监测成果为依据,基于现场观测的数据进行分析、处理和统计推断方法,形成一个综合的边坡变形失稳的预警模型,从而能更好更全面地对边坡失稳给以科学的解释和工程应用合理的建议。

The development of high slope monitoring and prediction technology is introduced in this article.The framework of GIS-based high slope monitoring and prediction model is brought forward,which integrated by Monitoring module,Calculation and analysis module and evaluate module.3D precise geological model,safety evaluation and based on in-situ investigation information prediction method as the key technology of GIS-based high slope monitoring and prediction model are expounded as well.
