摘要: 在复杂地形开展下放及提升绳索救援过程中,准确计算系统荷载是评估安全风险、优化救援系统配置方式的基础。通过对典型下放及提升绳索救援物理模型进行力学分析,利用绞盘方程建立复杂地形条件下,下放及提升绳索救援系统荷载的数学模型。利用模型,对下放及提升救援系统的不同环节开展分析,合理优化救援系统设计,通过降低系统荷载,提高救援行动安全性和效率,避免系统配置的盲目性。

Abstract: Abstract: Accurate calculation of the load in lowering and hauling system during complex terrain rescue is the basis for evaluating security risks and optimize rescue system configuration. Through the mechanical analysis of the typical physical model of lowering and hauling systems in rope rescue, using the capstan equation, the mathematical model of the load of lowering and hauling system under complex terrain conditions was established. Using the mathematical model to analyze the different parts of the lowering and hauling system, optimize the design of the rescue system, improve the safety and efficiency of rescue operations by reducing system load, and avoid the blindness of system configuration.
