摘要
地质灾害的发生一般是地形地貌、岩土体类型、地质构造、降雨、人类工程活动等综合因素作用的结果,从双牌县地质灾害详细调查的统计数据及分析来看,该县的地质灾害主要与上述因素的某个侧面关系较大,如地形地貌的坡形和坡度、降雨的年降雨量、人类工程活动强度分布区域等与地质灾害发生次数的关系;而与上述因素的其他侧面并无关系或关系甚微,如降雨集中区并不一定是地质灾害发生较多的区域。文中也分析了地质灾害详细调查中数据来源的局限性。
The occurrence of geological hazards is generally the results of topography, soil type, geological structure, rainfall and human engineering activities factors, from the point of view of statistical data and analysis of detailed geological disasters investigation of Shuangpai County, a side of the county's geological hazards are mainly associated with the larger, such as topography slope form and slope gradient, rainfall annual rainfall, human engineering activity intensity distribution area and geological hazards occurrence; and with the factors of the other side and no relationship or have little relationship, such as rainfall concentrated area is not necessarily of geological disaster often happens in the area. In this paper, the limitations of the data source in the detailed investigation of geological hazards are also analyzed.
