帘式网在门头沟灵山路边坡落石防护工程中的应用

Application of Curtain Type Protective Net in Protection Engineering of Slope Rockfall of Lingshan Road,Mentougou

公路的边坡落石常给运输安全造成危害,对存在落石隐患的边坡进行有效防护能为公路的安全运营提供保障。传统的刚性边坡稳固阻挡技术存在工程量大、施工难、费用高等不足。以北京门头沟灵山路K7+530^+600段边坡落石防护工程为研究对象,经过前期勘察、方案论证、方案设计、工程应用等,成功将覆盖式帘式网应用于该路段边坡落石的防护。实践表明:在工程完工后的三个月时间里,成功拦截了质量为200,3 200,15 000 kg的落石,防护效果明显,确保了公路运输安全。

Rockfall along the road usually will cause serious harm to transportation safety, and effective protection of the slope with rockfall hazards can safeguard the safe operation of the highway. Traditional rigid slope stability blocking technology has some shortcomings like large work quantity,construction difficulties and higher cost and so on. Therefore,with research object of slope rockfall protection engineering in Lingshan Road section K7 ＋ 530 ~ ＋ 600, Mentougou, Beijing, preliminary investigation, program demonstration,project design,project application,etc. were carried out to successfully apply the curtain-covered protective net in the slope rockfall protection of this road section. Practice shows that within three months after completion of the project,the rockfall with mass of 200,3 200,15 000 kg are successfully blocked,so the protective effect is obvious,and the road transport safety can be protected.
