Dangerous falling rock protection net setting method
The invention relates to the technical field of slope protection, and discloses a dangerous rock falling rock protection net setting method to solve the technical problem that a dangerous rock body slope passive protection net is difficult to set. The method comprises the steps: carrying out aerial photography on a dangerous rock body slope through an unmanned aerial vehicle, constructing dense point cloud information of the dangerous rock body slope according to aerial photography images, and generating a dangerous rock body slope model; delineating a rockfall area and estimating the rockfallvolume by utilizing a dangerous rock body slope model, acquiring motion characteristic parameters by combining a field test, simulating a rockfall track under the condition of no protective net, andacquiring rockfall motion characteristics; formulating a passive protection net layout scheme according to the rockfall motion characteristics; carrying out rockfall simulation on each passive protection net layout scheme, carrying out statistics on a corresponding rockfall interception rate, rockfall impact energy escaping to the vicinity of a protection object and the protection net cost, and evaluating a risk level and a cost level of each passive protection net layout scheme; and finally, determining an optimal scheme for laying the passive protective net according to actual engineering requirements and corresponding evaluation results.
本发明涉及边坡防护技术领域，公开一种危岩落石防护网设置方法，以解决危岩体边坡被动防护网设置困难的技术问题。本发明方法包括：利用无人机对危岩体边坡进行航摄，根据航摄图像构建危岩体边坡的密集点云信息，生成危岩体边坡模型；利用危岩体边坡模型，圈定落石区域，估算落石体积，并结合现场试验获取运动特性参数，模拟无防护网情形下的落石轨迹，获取落石运动特征；根据落石运动特征制定被动防护网布设方案；对各被动防护网布设方案进行落石模拟，统计相应的落石拦截率、逃逸至防护对象附近的落石冲击能量和防护网成本，评估各被动防护网布设方案的风险等级与成本等级；最后根据实际工程需要和相应评价结果确定布设被动防护网的最佳方案。
