A STUDY ON THE DISTRIBUTION FEATURES OF EARTHQUAKE LIQUEFACTION OF SILT-LAYER BASED ON THE STANDARD PENETRATION TEST IN KUNMING

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.
