G316陕西段地质灾害及对策分析

随着公路建设的不断发展,公路沿线地质灾害越来越多,危及公路的安全和正常运营。论文通过对G316国道陕西段地质灾害详实调查,在分析自然条件和地质条件的基础上,公路沿线地质灾害具有种类多,分布广、活动频繁,危害大的特点,常冲毁道路、耕地、房屋,危及人民的生命财产安全,同时研究了该段公路沿线地质灾害的分布特征、形成机制、危害及对策措施。研究表明,该段公路的地质灾害与工程地质条件、公路本身建设及人为因素等因素有关。所以,应结合上述特点因地制宜地治理灾害,达到治理灾害和保持公路生态环境相协调为目的。

Analyse on geologic hazard and prevention countermeasure along G316 in Shaanxi Province

With the development of highway, the geologic hazard is rapidly increasing, and it is menacing highway＇ s secruity and normal operation. We investigated the geologic hazard along the Shaanxi seotion of G316, geologic hazard has the charcateristics of distributing wide, high frequency, destructiveness, often destroying roads, farmingland, houses and putting people＇s lives and property in danger. Then, their distribution characteristics, forming mechanism, harm and countermeasures are researched.The results show that the highway＇ s geologic hazard can be related to engineering geology condition, building, factitious factor ect. According to the above, we repair hazard in adjusting measures to local conditions, and reach the aim of environment in harmony with hazard control.
