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。
The rational arrangement of the three-dimensional monitoring system of high slope stability can improve the reliability of the slope body monitoring and save engineering monitoring cost while ensuring the safety and stability of the slope. Based on the basic principle of optimal control theory, based on the three-dimensional numerical simulation, based on the reinforcement and optimization of prestressed anchor cable, a comprehensive optimization layout method of prestressed anchor cable monitoring system and inclinometer is proposed to realize slope reinforcement And prestressed anchor cable monitoring system and inclinometer joint monitoring and warning, and relying on a highway in Guangdong slope engineering carried out the optimal design. The results show that this optimization method can reasonably utilize the materials and space, control the construction cost, and prevent the phenomenon of repeated monitoring and missed detection effectively, so that the monitoring area covers the slope body to the maximum extent and effectively monitors the slope body.
