Rapid development of new deformation sensors and, at the same time, the growing concern regarding public safety, efficient production, and environmental protection, call for a new approach to the design and analysis of multi-sensor monitoring schemes. The design must be based on a good understanding of the physical process (mechanism) of deformation, delineation of expected stable zone, and on a good understanding of the sources of errors and limitations of various monitoring techniques. The applicant and his research team at the University of New Brunswick (UNB) have been involved in the development of new techniques and methods for monitoring and modeling of structural and ground deformations since 1970s. Recent developments include a generalized method of geometrical analysis of deformation; the ALERT software package for automated data collection and displacement evaluation; deterministic modeling and prediction of ground subsidence in mining areas, and the concept of using deterministic modeling in the design of monitoring schemes. The long-term objective of the proposed research is to expand and consolidate the above developments to create an intelligent Integrated System (IS) for a systematic approach to monitoring, modeling, and physical interpretation of structural and ground deformation. Over the next five years, the research will concentrate on the following components of IS: (1) evaluation and enhancement of new monitoring technologies focusing on the ground-based radar interferometry; and (2) separability concept in selecting the best fitting deterministic deformation model in the integrated analysis of deformation. The development of the Integrated System will be tested on real-life monitoring projects, which can provide reliable monitoring data. These include Cortez Hills open pit mine in Nevada, PCS potash mine in New Brunswick (extraction of potash, salt, water, and gas), deformations of large earthen dams in California, and a large dike of a toxic tailing pond at KGHM Copper mine in Poland.

快速开发新的变形传感器，同时，人们对公共安全，有效生产和环境保护的日益关注，呼吁采用新的方法来设计和分析多传感器监测方案。该设计必须基于对变形的物理过程（机制），预期稳定区域的描述以及对各种监测技术的错误和局限性的良好理解。自1970年代以来，新不伦瑞克大学（UNB）的申请人及其研究团队参与了监测和建模的新技术和方法。最近的发展包括一种变形的几何分析方法。用于自动数据收集和排量评估的警报软件包；采矿区中地面沉降的确定性建模和预测，以及在监视方案设计中使用确定性建模的概念。拟议的研究的长期目标是扩展和巩固上述发展，以创建一个智能的集成系统（IS），用于系统地监视结构和地面变形的系统方法。在接下来的五年中，该研究将集中于IS的以下组成部分：（1）评估和增强着针对地面雷达干扰法的新型监测技术； （2）在变形综合分析中选择最佳拟合确定性变形模型时的可分离性概念。集成系统的开发将在现实生活中的监视项目上进行测试，该项目可以提供可靠的监视数据。其中包括内华达州的Cortez Hills开放坑矿，新不伦瑞克省的PCS钾盐矿（钾，盐，水和气体的提取），加利福尼亚州的大土水坝的变形，以及波兰KGHM铜矿的有毒尾巴的大堤坝。
