某铁路线崩塌落石危险性评估与防护措施研究

采用三维激光扫描技术建立高精度地形模型,运用Rocpro3D软件对某铁路线某点位#3危岩区滚石影响范围及防治措施进行模拟研究.结果表明:现有防护措施下,落石滚落过程中存在明显的归槽现象,公路处滚石灾害等级为高和非常高,下部铁路处灾害等级为中等和高,受滚石威胁较大;在坡脚处补充三道被动防护网后,显著降低了落石滚落至铁路路...

Risk Assessment and Protection Measures for Rockfall of a Railway Line

The terrain model with high precision was established by use of 3D laser scanning technology, and Rocpro3D software was used to simulation study the influnce of rockfalle and the control measures in #3 dangerous area in the section of a railway line. The result shows that, under the existing control measures, there has an obvious contraction during rock falling so that the rockfall hazard along the highway ranks high and very high and that along the railway at the lower part ranks middle and high, thus the highway and railway are subject to large threat of rockfall. After three passive nets added the slope toe, it significantly reduced the probability of rocks rolling to the railway subgrade.
