皖东某建设工程地质灾害危险性分析

位于皖东某地的一项建设工程,是当地集中用地面积最大的建设项目之一,由于建设场地原为一处废弃的采石场,地跨低山丘陵和山前坡岗地,地形高差大,断层较发育,地质条件比较复杂,人类工程活动比较强烈,存在较大的地质灾害隐患。作者根据建设场地所处的地形、地质条件和人类工程活动,认为现有的人工岩质边坡基本处于不稳定状态,在断层交汇处附近地下很可能存在岩溶洞穴,分析了建设工程可能引发或遭受的地质灾害主要是崩塌、滑坡、岩溶塌陷、回填土不均匀沉陷和断裂活动的影响等类型,建议建设单位采取有效措施加以防范。

Geologic risk assessment of an on-going building engineering in the East Anhui province

In the east Anhui province,there was an engineering project under construction,which belonged to one of the projects with the largest land use.As it was located on an abandoned quarry,spanning low hills and piedmont areas,and with large elevation differences and development of faults,the background geologic conditions were complex.Moreover,human engineering activities were very intensive in the area,therefore there would be many hidden geological risks.According to the topographical features,the geological ...
