| 摘 要： | 根据野外调查，并综合前人的研究资料，对鲁中南地区第四纪晚期断裂活动进行了分析，研究表明，鲁中南隆起区第四纪断裂活动具有时空不均匀性，主要表现为第四纪时期断层活动强度变化和断裂活动的群集性以及第四纪晚期断裂活动段分布的局限性上。对于鲁中南地区而言，活动断层可以分为中更新世中期（500kaBP)至晚更新世初期（90kaBP)活断层和晚更新世中、晚期至全新世早期活断层两类；其中前一类（主要是中更新世断裂）断裂数量较多，分布较为广泛，而晚更新世晚期以来的活动断裂段的数量较少，分布较局限。它们对地震的控制能力不同，前者可控制5．5级左右的地震，而后一类可控制6－7级地震的发生。

| Abstract: | The authors have performed a series of researches on seismogeology,Quaternary structure and strata,and accomplished several tens of projects on engineering geology and engineering earthquakes in the middle and south region of Shandong Province in recent years.The results indicate that the Quaternary fault activities in this region shows unhomogeneity in temporal and spatial domains which were mainly displayed by the variations in the intensity and the clustering of fault activities and the limitation of the distribution of the late Quaternary active fault segments.As for the middle and south region of Shandong Province,active faults can be divided into two types:the first type is composed of active faults which were active between the mid time of mid Pleistocene and the early period of late Pleistocene,and the second includes active faults which were active between the mid and late periods of late Pleistocene and the early period of Holocene.The above mentioned two types of active faults can control the occurrence of earthquakes with different magnitudes,the former can control the occurrence of earthquakes with magnitude of about 5 5,while the latter with magnitudes between 6 and 7. |
