山区沿河公路地质风险分类
|
摘要
山区沿河公路的不良地质多发路段占公路里程比例高,是公路工程防灾减灾学科的重要方面。为了在公路养护和管理部门中推广未雨绸缪的地质安全观,基于文献分析和实地调研,引入"公路地质风险"的理念,并对地质风险及相关重要术语进行了科学界定;在总结已有地质风险分类模式的基础上,基于山区公路破坏的受力特征,系统构建了山区沿河公路地质风险类型及其力学模式,并有针对性地提出了各种山区沿河公路地质风险类型的易发部位和抗毁措施。把山区沿河公路地质风险类型分成"推挤"、"牵拉"、"冲"、"淤"、"渗"等5大类型,可供深入地研究公路地质灾害形成的力学机制参考。提出的各种地质风险类型的易发部位和抗毁措施可为山区沿河公路减灾决策提供支持。
The unfavorable bad geology sections accounts for a high proportion of the mountain riverside highway,which is the most important aspects of the highway engineering disaster prevention and mitigation subject.In order to promote the geological security concept in the highway maintenance and management departments,based on the literature analysis and field investigation,the idea of "highway geological risk" is introduced,and the geological risk and related terms are scientifically defined.At the conclusion of summarizing the existing geological risk classification model,based on the damage mechanical characters of mountain highway,it systemically constructs the geological risk types and mechanical model for mountain riverside highway,and then provides some anti-destroy measures according to the prone happening parts for the specific geological risk.The mountainous area riverside highway geological risk is classified into five major types,i.e.,"pushing","pulling","impacting","silting" and "seepaging",which could be available reference for further researches on the formation mechanical mechanism of the highway geological disasters.The proposed prone happening parts and anti-destroy measures according to the specific highway geology risk types can be considered for supporting the disaster mitigation decision-making process in mountain area highway.
