某高陡危岩边坡的综合整治

The comprehensive measure to a highsteep slope

京珠高速公路粤境北段位于粤北大瑶山中,地势险要,地形复杂,地层条件差,人为活动频繁。如何保证区内既有公路的正常通行、高速公路的建设施工安全及高速公路的运营安全是一个较为突出的问题。文章介绍了采用SNS主动防护网对高陡危岩边坡进行浅表层加固、SNS被动防护网对坡面滚石进行拦截(和堆存)、预应力锚索及锚墩对坡体深层滑坡进行治理的综合整治措施。其工期短,功效显著,对类似工程具有较大的借鉴意义。

The high way from Beijing to Guangzhou crosses Dayao Mountain in the north of Guangdong province.One problem is how to ensure the highway unobstructed and safe in transportation and construction.This paper introduces a method to protect rolling stones with SNS passive protecting net and to protect high and steep slopes with SNS active protecting net.Through the example,the comprehensive measure also has been introuced.Because this engineering is timesaving and efficient,it is helpful to other similar projects in our country.
