摘要
贵州是全国地质灾害防治重点省份,地质灾害多发、易发、频发。开阳县为贵州省地质灾害防治重点县,全县地质灾害发育显著,种类多样,分布范围广,规模不一,受地质环境和人为工程活动影响,地质灾害防范压力较大。本文通过对开阳县内已发生的崩塌地质灾害及现有崩塌(危岩体)地质灾害隐患进行详细的调查,分析区内崩塌地质灾害的发育特征及成因分析,为相邻地区地质灾害防治及国土空间规划提供基础地质依据。通过调查发现,开阳县崩塌(危岩体)主要受内因及外因两方面因素影响。内因主要受地形地貌、地层岩性、地质构造影响。外因主要受根劈作用、气候条件、气象因素、采矿工程活动影响。
Guizhou is a key province for the prevention and control of geologic disasters,and geologic disasters are frequent,easy to occur and frequent.Kaiyang County is the key county of Guizhou Province for geologic disaster prevention and control,and the development of geologic disasters in the county is remarkable,with diverse types,wide distribution range and different scales,which are affected by the geologic environment and anthropogenic engineering activities,and there is a greater pressure on the prevention of geologic disasters.In this paper,through the detailed investigation of the collapse geological disasters that have occurred and the existing collapse(dangerous rock body)geologic disaster potential sites in Kaiyang County,we analyze the development characteristics and causes of collapse geologic disasters in the area,so as to provide basic geologic basis for the prevention and control of geologic disasters in the adjacent areas and the national land spatial planning.Through the investigation,it is found that the collapse in Kaiyang County is mainly affected by both internal and external factors.Internal causes are mainly influenced by topography,stratum lithology and geological structure.External factors are mainly influenced by root splitting,climate conditions,meteorological factors and mining engineering activities.
