摘要: 根据10余项工程中代表性钻孔岩芯分析,参照2000多个工程钻孔资料,对比了苏州市50m以浅晚第四纪各沉积层的成因类型、形成时代、岩性及其物理力学性质,并依地基工程要求,对沉积层进行了合理划分。阐述了本区4万年来古地理的环境变迁,绘制多时段的古地理图,摸清了本区各土层的空间分布规律及结构变化特征,在此基础上编制出"天然地基工程地质条件分区图"和"桩基工程地质条件分区图",论述了天然地基和不同桩基区的工程地质条件及施工注意事项。

Abstract: Based on the analysis of the bore cores of more than 10 projects and the drilling materials of more than 2000 bores, the shallow soil layers within 50 m deep are analyzed, including the origin, time, composition and the physical mechanics properties. The terminology table of the soil layers is made, according to the demand of the foundation engineering. The distribution maps of engineering geologic condition for natural foundation and for pile foundation are compiled in light of spatial distribution and structural characteristics of soil layers. The study is of great signification for engineering construction of Suzhou urban district and the southern part of the Changjiang River delta.
