摘要
绵竹市清平镇、汉旺镇一带是"5·12"汶川大地震的重灾区之一,灾后形成了大量的滑坡、崩塌、泥石流等次生地质灾害遗迹,尤其"8·13"清平特大群发性泥石流影响巨大.四川绵竹清平—汉旺国家地质公园是以清平—汉旺地质灾害链为线索,以地质灾害防治工程和群测群防体系为重要内容建立起来的地质公园.2023年通过野外系统地质遗迹调查研究,查明了现存环境地质遗迹类型、特征及分布范围,通过对区内地震力、地层岩性、地质构造、地形地貌、降雨与地下水和人类工程活动等地质灾害形成影响因素的分析,科学划定公园地质灾害易发区,为地质灾害预报、预警、防治提供科学依据.
Abstract
The area of Qingping Town and Hanwang Town in Mianzhu City is one of the worst-hit areas of the"5·12"Wenchuan earthquake.A large number of landslide,collapse,debris flow and other secondary geological disasters have been formed,especially the"8·13"Qingping massive mass debris flow has a huge impact.The Qingping-Hanwang National Geopark in Mianzhu,Sichuan Province,is a geopark based on the Qingping-Hanwang geological disaster chain and the geological disaster prevention engineering and group survey and group prevention system.The types,characteristics and distribution range of existing environmental geological relics were identified through field systematic geological heritage investigation in 2023.Based on the analysis of earthquake force,stratigraphic lithology,geological structure,landform,rainfall and groundwater,human engineering activities and other factors affecting the formation of geological disasters in the park,the geological disaster prone areas are designated,which provides scientific basis for geological disaster prediction,early warning and prevention.
