摘要
山东沿海与近海地区发育有多种地质灾害。通过对该地区存在的主要地质灾害进行系统的野外调查、统计与分析,编绘了研究区及邻域的地质灾害分布图,总结了各种地质灾害的空间发育特点。在成因分析的基础上,将研究区内的地质灾害划分为地震、地面变形、边坡灾害、流体灾害、水土质变异、气相灾害、不稳定沉积和其它地质灾害因素8类,并进一步细分为33种。作者从地质灾害的形成动力、成生关系、成灾过程、成灾关联性、成灾可控性及其危害性出发,阐述了各种地质灾害的属性特征。为防灾减灾提供了决策依据。
There are many kinds of geological hazards in the coastal and offshore areas of Shandong Province. Based on systematic survey, and statistic analysis of the main geological hazards, a map showing the distribution of geological hazards was compiled for the areas, and the development features of the geological hazards in space were discussed. Based on the analysis of the causes of their formation, the geological hazards were classified into thirty three kinds and eight types. The eight types are earthquake, land deformation, slope hazard, fluid hazard, the variation of water-soil quality, gas geological hazards, unstable deposit and other geological hazard factors. Their characteristics were expounded in terms of their formation dynamics, genesis, generation process, relationship, controllability and harmfulness of, thus providing a foundation for decision-making for the prevention and mitigation of hazards.
