【摘要】 徐州、铜山地区近代地壳稳定,近期区内直接发生大地震的可能性不大。历史上曾受邻区地震波及破坏,但近期这种危险也小。推测一旦遇强震本区可能产生断层反射地震波、砂土液化、地基沉陷和边坡不稳等不良现象。可见本区为地基稳定、震害较小的山丘类型,可能产生地基滑陷、震害中等的平原边缘和地基软弱、震害和次生灾害较多的平原中部类型。应采取避开断层和陡崖、加深基础和固坡等措施。更多还原

【Abstract】 In recent time, the earth’s crust in Xuzhou-Tongshan area is stable , therefore , the possibility of an earthquake occurring directly is verylittle. In the past, this area was destroyed by the neighbour earthquakes, but, in the next years, such dangers are still very small.If a big earthquake happened, many bad phenomena could appear in this area: Such as fault reflect seismic wave; sand,silt and clay liquefaction; foundation subsidence and side slopes unfix, etc.The earthquakes in this area may be divided into three types: hilly land with solid foundation and less earthquake damage; the plain verge where foundation slump and middle earthquake damage may occur; the central plain where foundation is weak, there are more earthquake damages and secondary calamities.And, precautions should be taken against avoiding parry faults and bluffs, deepening foundation and strengthening side slopes, etc.更多还原
