| 摘 要： | 盘锦市场地土在地震力作用下极易产生液化现象．为了预防灾害，保护人民的生命和财产的安全，有必要对盘锦市场地土进行液化判别，并对城市各区域进行场地液化分区．笔者收集了盘锦市区300多个勘探钻孔资料，并分别对其进行了液化判别以及液化指数的计算，并根据相应的液化指数对盘锦市区进行了液化分区．结果表明，在7度抗震设防烈度下，盘锦市部分场地会产生轻微和中等液化区；8度抗震设防烈度下，盘锦市会产生大面积液化区．所以必须考虑采取相应的抗液化措施．

| Abstract: | The article first points out the fact that the ground soil in Panjin easily produces liquefaction phenomena on seismic force effect.To avoid disaster and protect lives and property,liquefaction differentiation and liquefaction zoning to the ground soil in Panjin are of great necessity.Three hundred exploration drill-hole data in Panjin was collected;liquefaction index and liquefaction judgement were calculated;liquefaction index and liquefaction zoning for Panjin were carried out.The result indicates that partly ground at 7 degree earthquake intensity in Panjin will undergo light and middling liquefaction zoning;a lot of area will undergo liquefaction zoning at 8 degree earthquake intensity.Therefore corresponding measures must be taken. |
