摘　　要：为了查明工程建设区和规划区地质环境条件基本特征,分析论证工程建设区和规划区各种地质灾害的危险性,通过进行现状评估、预测评估和综合评估,对其潜在的危险性进行客观评价,提出防治地质灾害措施与建议,并给出建设场地适宜性评价结论,从根本上达到防灾、减灾的目的。本文以唐山市某小学为例,通过调查研究与分析,确定评估范围和评估级别,分析论证地质灾害的发生、发展规律和致灾因素,通过综合评估,最后得出建设场地为适宜的结论,并提出场地基坑开挖时做好支护措施和进行抗震设防的建议。In order to find out the basic characteristics of the geological environment conditions in the project construction area and the planning area, and to analysis and demonstrate the risk of various geological disasters in the project construction area and the planning area. through the assessment of the status quo, prediction assessment and comprehensive assessment, the potential risk was evaluated objectively. The measures and suggestions for prevention and control of geological disasters was put forward and suitability evaluation conclusion of the construction site was given, The purpose of disaster prevention and disaster reduction were achieved fundamentally. In this paper, a primary school of Tangshan was taken as an example, through the investigation and analysis, we determine the scope and level of the assessment, and analyze and demonstrate the occurrence, development laws and disaster-causing factors of geological disasters. through comprehensive evaluation, the conclusion that the construction site is appropriate, and the support measures and seismic fortification of the foundation pit excavation are proposed.
