摘 要: | 柔性防护网用于边坡落石防护具有独特的优越性,除了制造、施工、配置之外,防护设计方案的合理与否同样影响其防护效果。以某公路边坡为例,采用三维激光扫描技术对公路边坡进行了地形扫描,结合现场地质调查,运用数值模拟软件对边坡落石运动进行计算分析,获取落石运动轨迹、速度、能量以及弹跳高度,并在此基础上进行了落石防护设计,降低了柔性防护网失效可能性。

Rockfall Control Design Based on Soft Net System |
| |
Abstract: | Soft net system (SNS) has unique superiority when it is applied for rockfall control. In addition to its manufacturing, construction and configuration, wether the design scheme is reasonable or not is also important. Taking a highway slope as an example, 3D laser scanning technique was used to scan the landform thereof and, combined with field geological investigation, the rockfall was calculated by numerical simulation software. Based on the motion trajectory, velocity, energy and bouncing heigtht, which were obtained by the calculation herein, the rockfall controll design was conducted to let the soft net system less likely lose its efficacy. |
