新沂地质构造图(国外英文资料) Bedrock geology and construction Proposed venue located in the eastern part of the tanlu fault zone xinyi - suqian section graben, the tanlu fault zone is the eastern part of our country famous deep fault belt, the north north east to wear cut by the archean crystalline basement of the north China block, xinyi, suqian section chief is composed of five roughly parallel to the main faults, which constitutes a wide five main faults, about 30 km two willing to clip a single structure, complicated structure, the new activity is strong, the basal medium stiffness is higher. Tanlu fault zone is in strong compression and dextral twist of tectonic stress field, because of its normal stress, shear stress is big, easy to accumulate the energy of the earthquake, and difficult to to release in the form of medium and small earthquakes, so this earthquake intensity, low frequency. In 1668, the 8.5-magnitude earthquake occurred in the county of tanlu in the county of tanlu, which is adjacent to xinyi, the northern part of the city. 0 on September 2, 1995 in shandong cangshan m M5.2 earthquake, in June 2003, the shandong Qingdao MC4.3 magnitude activity of groups of small earthquakes, earthquake activity in recent years show that the region is relatively frequent, has been as a key monitoring area earthquake hazards. The west side of the tanlu fault zone xinyi - suqian section of sino-korean paraplatform huai Taiwan depression of huaibei in transitional zone of xuzhou - province in arc fault fold belt, structural feature is mainly for the NE - NEE to fold structure and in the same period time of fault structure, strata are mainly sinian system - quaternary carbonate rock, clastic rock and sand inclusion of cohesive soil layer. The tanlu fault zone xinyi, suqian section of the qinling fold system to the dabie mountains, Sue subei - jiaonan glue fold belt of anticline in the east China sea - GanYu anticlinorium, the stratigraphic distribution, mainly archaean group -
