SNS柔性防护网在北京崩塌防治工程中的应用

The Application of SNS Flexible Net in Beijing Slope Protection Project

崩塌是北京山区汛期最常见的一种不良地质现象,北京地区尤其西部和北部山区崩塌的形成主要与长期以来人类工程活动密切相关,通过工程实践与经验积累,柔性防护网技术在国内已经使用的越来越多。这种以钢丝绳为主要构成特征的SNS边坡柔性防护系统,已在铁路、公路、水电站、矿山、市政工程的崩塌落石、浅层坍滑、风化剥落和泥石流等坡面地质灾害防护中得到广泛的推广应用,本文以怀柔老公营崩塌治理工程为例,介绍了SNS柔性防护网在北京市边坡防治工程中的应用。

The flood collapse in Beijing mountain area is one of the most common geological hazards, especially the collapse of the western, northern mountainous areas in Beijing is closely related to the long-term human engineering activities. Through engineering practice and experience accumulation, the flexible net technology has been used more and more in China. The SNS flexible protection net is mainly composed of steel wire rope, which has been used in the railway, highway, hydropower, mining, municipal engineering to prevent the collapses of the rockfalls, shallow slumping slide, weathering flake and the slope. Taking Huairou Laogongying collapse protection project as an example, this paper introduces the application of SNS flexible net in the slope protection project.
