上海市崇明岛浅层砂土、粉土分布探讨

DISTRIBUTION OF THE SHALLOW SANDY SOIL AND SILTY SOIL OF CHONGMING ISLAND, SHANGHAI

通过对崇明岛内大量勘探资料的分析研究,本文分析了岛内浅层砂土、粉土的分布特征,并根据岩性及静力触探指 标对其进行详细分类,找出了每类土的典型静力触探曲线,最后探讨了各类土的液化问题。

Through detailed analysis of data obtained from engineering geological explorations at Chongming Island, this paper characterizes the distribution of both the shallow sandy and the silty soils present in the area. The authors then classify each soil according to its lithology and penetration resistance, and present several typical penetration curves. At the end, this paper discusses the liquefaction characteristic of each soil.
