摘要： 高边坡稳定性三维监测系统的合理布置可提高边坡体监测的可靠性，在确保边坡安全稳定的同时节省工程监测成本。基于最优控制理论的基本原理，通过三维数值模拟，在预应力锚索加固优化的基础上，提出了一种预应力锚索监测系统和测斜仪的综合优化布置方法，以实现边坡加固和预应力锚索监测系统与测斜仪的联合监测预警，并依托广东某高速公路的边坡工程进行了优化设计。结果显示，此种优化方法能合理利用材料和空间、控制工程费用，并有效防止重复监测、漏测等现象，令监测区域最大程度地覆盖边坡体，实现边坡体的有效监测。

Abstract: The appropriately distributed of transducers in the three dimensional monitoring system for the stability of a high slope can improve the monitoring reliability, reduce the monitoring cost as well as ensure the safety of the cut slope. This paper presents an optimization design of the monitoring system of combining the prestressed ground anchor monitoring probes and the slope inclinometers. The optimization design is based on the application of the optimality principles as well as the three dimensional numerical analysis. This optimized system was applied in the stability monitoring of an expressway high cut slope. The results indicate that this optimized method can effectively reduce the use of construction materials and cost. The coverage of the monitoring system can be maximized and the monitoring errors, such as, data loss, repeated data, can be minimized.
