延庆县玉海路崩滑塌灾害的危险性评价及防治对策

Risk Evaluation and Protecting Method of the Collapse and Landslide Hazards on Both Sides of Yuhai Road in Yanqing County,Beijing

北京市延庆县玉海路是通往玉渡山自然保护区的必经之路,由于其大部分为开山路段,存在大量不稳定边坡;公路沿线边坡缺乏相关配套的灾害防治工程,经常发生崩塌、滑坡等地质灾害。本文介绍了玉海路沿线崩滑灾害特征,综合评价了其灾害危险性,进行了公路危险性分段,提出了防治对策。

Yuhai Road is the gateway to Yudu Mountain Nature Reserve,and Most of the road is the mountainous section.There are a large number of unstable slopes with broken rock and geological structures.The road was built along the slope without disaster prevention project,so the collapse and landslide hazards often happen.In the past,pedestrians and vehicles have a greater threat although no casualties.This paper describes the characteristics and development of the collapse and landslide hazards along the Yuhai Road.With the introduction of two evaluation projects including susceptibility and harmful levels,the comprehensive evaluation and prevention method of disasters are discussed finally.
