东华理工大学毕业设计 (论文） ABSTRACT 东华理工大学毕业设计 (论文） 摘要 摘 要 本文是以建德市下涯镇农民安置房为背景，通过对评估区进行野外实地测绘调查，分析论证评估区各种地质灾害的危险性，进行现状评估、预测评估和综合评估。论文的主要内容为分析了评估区区域地质、地质构造、区域植被及地质灾害分布以及发育特征、水文地质、工程地质以及地壳稳定性等地质环境条件，在此基础上通过地质灾害危险性现状评估、预测评估和综合分区评估,对包公坞建设安置房项目工程的地质灾害作出危险性评价。分析结果表明评估区地质环境条件复杂程度为复杂，且地质灾害危险性评估等级为三级评估;根据已有资料和现场野外调查，评估区范围内现状地质灾害不发育；地貌类型属于丘陵地貌，地形地貌条件较简单；地质构造简单；拟建场地平整过程中AB、BC、DE、EF区段山体开挖引发崩塌、滑坡地质灾害的可能性中等，地质灾害危险性中等；建设用地基本适宜；其它区段工程建设引发和遭受地质灾害危害的可能性小，地质灾害危险性小，建设用地适宜。评估区属中国东南部地震活动相对稳定区。评估区附近发生地震，且评估区地震动峰值加速度＜0.05g，相当于地震基本烈度小于Ⅵ度，属区域地壳稳定区。对评估区地质灾害类型及特征进行现状分析、并对拟建工程可能产生的地质环境条件和建设过程中可能诱发、加剧以及遭受的地质灾害等进行预测评估和综合研究，论文可为建设项目的顺利进行提供依据。 【关键词】：地质灾害危险性； 评估建设项目； 地质环境条件；气象水文 ABSTRACT This article is based on Xiaya town of Jiande City farmer resettlement housing as the background, through the assessment of areas under field mapping surveys, analysis and appraisal of geological hazard assessment areas of risk, to assess the situation, forecasting and integrated assessment. The main contents of the assessment district for the analysis of regional geology, geological structure, the regional distribution of vegetation and geological disasters, and developmental characteristics, hydrogeology, engineering geology and environmental conditions and other geological crustal stability, on the basis of status through geological hazard assessment,forecasting and integrated assessment district assessments, Bao dock construction of resettlement housing project engineering geological disaster risk assessment made. Analysis showed that the assessment of the geological complexity of the environmental conditions for the complex, and geological hazard assessment level for the three assessment; based on the existing information and on-site field survey to assess the current situation within the area of geological disasters are not developed; landforms are hilly topography, terrain conditions is relatively simp
