Optimization Design for the Monitoring Instrunent of Dam Safety

大坝工程安全监测仪器优化设计,实质上是一个求解可行域上非连通、带约束的拓扑优化问题,需充分考虑全面、可靠获取反映大坝安全性状的真实信息,满足观测资料正反分析、病害诊断和健康评价等的目标,建立优化目标数学模型,设计优化实现算法,使得优化布置既有理论依据,又有可操作性.基于此目的,从监测系统布置优化基本目标出发,初步探讨了传感器数目(传感器类型和个数)优化和测点定位优化设计理论.

In the field of dam safety monitoring, optimization design of observation instruments is a topological optimization problem, which is non - connected, restrictive in the feasible region. To solve this problem, it is necessary that the obtained data represent factually the safety status of dam. The observations can be used to implement the analysis and feedback analysis, abnormity diagnosis and health evaluation. The mathematical models of optimization aim need to be built. The optimization algorithms need to be designed. Optimization design of observation instruments has theory foundation and maneuverability. According to the basic aim of optimization design of observation instruments, this paper proposes the design theory on optimizing the number and type of sensor, the position of observation point.
