摘　　要：通过地形地貌分析、钻孔勘探、地层分析、剪切波速测试等手段,对六安市地震小区划场地进行了场地类别划分,结合土层分布特征及地震地质资料,划分了工程地质分区。具体划分为三个工程地质区,分别为:侵蚀剥蚀低丘坡积洪积粘性土、基岩分布区、冲积浅丘状平原粘性土分布区和冲积淠河漫滩、阶地-支流河谷平原软土、粘性土分布区。In this paper,by means of topography and geomorphology analysis,drilling exploration,stratigraphic analysis and shear wave velocity testing,etc.,the site classification of the seismic zone in Lu'an City is divided.Combined with the distribution characteristics of soil layers and the seismic geological data,the paper divided the micro-zoning site into three engineering geological areas,which are the erosion shallow hill with the slope and flood clay soil and bedrock area,the shallow hilly and the floodplain with alluvial clay soil area,the valley plain of terrace tributary with soft soil and clay soil area.
