摘　　要：中宁县地处卫宁地震带西段,历史上是地震多发、强度较大的地区。地震引起的粉-砂土液化现象导致地基失效,通常伴随大规模的地面塌陷、滑移、地裂和喷水冒砂等现象。为了查清中宁县地基土地震液化的程度及危害,选用了全县范围内12个场地的岩土工程勘察报告的数据资料进行地震液化评价。Zhongning County located in the west section of Wei-ning seismic belt is seismically-active and intensive area in history.silty-sandy soil liquefaction phenomenon caused by earthquake led foundation failure,and commonly accompanied by large-scale ground subsidence,slip,ground fissures,sandboils and watersprouts phenomena are presenfed.In order to identify the extension and hazard of foundation soil seismic liquefaction of Zhongning County,geotechnical engineering investigation reports data selected from 12 sites within the county to evaluate seismic liquefaction are used.
