摘    要:
通过收集到的昆明地区700个高层建筑的勘探钻孔及水文钻井资料,建立了昆明地区工程地质综合数据库,对昆明市及昆明市粉土层工程地质条件进行了概述,介绍了昆明市粉土平面分布规律,及厚度,埋深规律统计。依据《建筑地基抗震设计规范》(GB50011)采用标准贯入试验判别法判断砂土的液化,根据标贯判别结果,结合昆明市平面地形图,利用Mapgis软件对昆明市粉土层进行了振动液化平面分区,根据液化的喷水冒砂现象,及对建筑物的危害程度,将其分为4个区(不液化区,轻微液化区,中等液化区,严重液化区),并找出液化区的分布规律。

关 键 词:粉土  工程地质条件  标准贯入试验  平面分区  昆明市

Abstract:
In this paper, according to the data of seven hundreds bore hole and well drilling the engineering geological properties of silt is summarized, and the two dimensional distributed regularities, the statistics of thickness and depth are introduce. According to the earthquake resistant design code of foundation ground (GB50011), the results of standard penetration test has been used in this paper to distinguish the silt liquefaction. In accordance with liquefaction distinguish outcome, the area has been divided into four regions,such as: non liquefaction zone,slightly liquefaction zone,moderate liquefaction zone,severity liquefaction zone)by mapgis software.
Keywords:Silt  Engineering geological condition  Properties standard penetration test  Two dimensional distributed regularities  Kunming city
