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.

新的变形传感器的快速发展，以及对公共安全、高效生产和环境保护的日益关注，要求采用一种新的方法来设计和分析多传感器监测方案。设计必须建立在对变形的物理过程(机制)、预期稳定区的划定以及对各种监测技术的误差来源和局限性的充分理解的基础上。申请人及其在新不伦瑞克大学(UNB)的研究小组自1970年代以来一直参与开发监测结构和地面变形并建立模型的新技术和方法。最近的发展包括变形几何分析的通用方法；自动数据收集和位移评估的ALERT软件包；矿区地面沉陷的确定性建模和预测，以及在监测方案设计中使用确定性建模的概念。拟议研究的长期目标是扩大和巩固上述发展，以创建一个智能综合系统(IS)，以系统地监测、建模和物理解释结构和地面变形。在未来五年内，这项研究将集中在以下几个方面：(1)评估和加强以地基雷达干涉测量为重点的新监测技术；(2)在形变综合分析中选择最佳拟合确定性变形模型的可分离性概念。综合系统的开发将在实际监测项目上进行测试，可以提供可靠的监测数据。其中包括内华达州的Cortez Hills露天矿，新不伦瑞克的PCS钾矿(开采钾盐、水和天然气)，加利福尼亚州大型土坝的变形，以及波兰KGHM铜矿有毒尾矿库的大型堤坝。
