济南市主城区地震地质灾害研究
|
摘要
地震地质灾害研究是地震灾害研究中的一项重要内容。通过对济南市主城区地层年代、岩土体特征、地形地貌条件等分析,在地质钻探和粉土颗粒分析实验基础上,采用标准贯入试验方法对济南市主城区砂土液化进行了判别,结果表明Ⅶ度烈度下济南市主城区西北部部分地区轻微液化,局部中等液化。研究表明,Ⅶ度烈度下济南市主城区发生滑坡、软土震陷、黄土震陷等地震地质灾害可能性较小,但局部可能发生崩塌、塌陷、地裂缝等地震地质灾害。
Based on the analysis of formation age,geotechnical characteristics, geographic and geomorphic conditions,adopting the SPT by means of geological drilling and soil granule test,the sand-soil liquefactions were discriminated.The results indicate that the liquefaction of some areas in the northwestern part of Jinan is slight and partly medium under the effect of earthquake whose intensity is about 7 degrees.It shows that the earthquake geological hazards,such as collapse,silt softening,loess collapsing,etc.are less likely to occur in the main urban area of Jinan.But the falling,subsidence and ground fissure are likely to hit parts of Jinan.
