对山东省几个考古发掘遗址进行了地震考古研究,着重对其中的自然变形现象进行识别和分析.其中,在济南郊区的大辛庄商代遗址中甄别出非构造变形的现象;在章丘城子崖龙山文化层中识别出砂脉充填裂隙;在滨州秦皇台商周文化层中发现槽壁上砂脉和槽底密集分布的砂管;在临淄齐国故城城墙分别鉴别出构造和非构造成因裂隙;在日照尧王城见龙山-战汉时期文化层中平行分布的砂脉裂隙组;在滕州薛国故城城墙识别出典型共轭剪切裂隙.上述自然变形现象集中显现于春秋-战汉期及以前的文化层中,且多表现为砂脉等地震液化痕迹,显示相当时期所在地区可能处于地震相对活跃期,上述推断部分得到微观分析资料证实.%The study conducted an earthquake archaeological research in recent four archaeological excavation sites in Shandong,focusimg on the identification and analysis of tectonic deformation phenomena.Non-tectonic deformation phenomena were found in the Daxingzhuang site of the Shan Dynasty in Jinan suburbs.In the Longshan cultural layers,Chengziya site,Zhangqiu City,sand veins filling fracture were recognized.Sand veins on the tank wall and sand pipe density on the tank bottom were found at the Shan and Zhou Dynasty cultural strata in Qinhuangtai,Binzhou City.The tectonic cause and non-tectonic cracks were identified in the walls of the former Qi City,Linzi.In Rizhao City,the parallel distribution of sand vein fracture groups were found at the Yaowangcheng site of the Jianlongshan-Warring States-Han Dynasties.Typical conjugate shear fractures were identified in city walls of the former Xue City in Tengzhou city.The above natural deformation phenomena appeared concentrated in the culture layer of the Spring and Autumn-the Warring States-the Han Dynasties and before,and characterized by the seismic liquefaction of sands and other traces,which indicates that the region might well be in seismic active periods.The above inference was partly confirmed by the data microscopic analysis.
