九环线平武段公路地质灾害分布规律研究
|
摘要
九环线旅游公路是地震灾区因地质灾害受损较为严重的一条公路,通过对沿线公路地质灾害的详细调查研究,依据灾害点的分布情况,结合区域自然地理和地质环境条件分析得出,沿线地质灾害的分布受其地形地貌、地层岩性、构造活动、地震作用、降雨、水库蓄水、人类工程活动、河流地质作用等诸多因素综合控制,但由于组合关系的影响,其分布特征在时间、空间上呈一定的规律.即在时间上具有周期不确定性、群发性、反复性;在空间上具有方向性、局部增强性、相关性.针对各个分布特征,提出了有关治理和预防的建议.
Jiuhuan tourist highway was seriously damaged due to geological desasters in earthquake disaster area;this paper presents a detailed investigation and study of the geological hazards along the highway.Based on the distribution of disaster points,combining with regional natural geographical and geological and environmental conditions,the analysis shows that the distribution of geological disasters are comprehensively controlled by many factors,such as topography and landforms,rocks,tectonic activities,seismic action,rainfall,reservoir water storage,human activity,rivers geological processes,etc.However,due to the combination of relations,its distribution characteristics show a certain law in the time and space.It is shown that the cycle of uncertainty,mass and recurrent in the time;directivity,local enhancement and rendered in space.Finally,some recommendations about management and prevention are presented for reference.
