| 摘 要： | 杭州湘湖地区为山前堆积、钱塘江冲海积与冲湖积相沉积环境,西南部软土发育,北部和东部砂性土为主,工程地质条件复杂.通过工程地质层特征、空间展布、物理力学性质和三维工程地质结构分析表明,软土中存在透镜状砂体、粉砂土中夹软土,构成较好的地下水通道和剪切滑动层.因此,在工程施工中应重点注意软土地基与砂土液化等不良工程地质问题,并建立监测预警体系,以免重大事故的发生.

| Abstract: | The sedimentary sequences in the Xianghu region of Hangzhou city,eastern China were characterized by fore-mountain,Qiantangjiang alluvial-marine and alluvial-lacustrine facies.In space,the southwestern region was majorly covered by soft soils,whereas the northern and eastern regions were mainly covered by sandy soils.Both resulted in the overall complication of the local engineering geological conditions.In this paper,analyses on the engineering geological features,their spacial distributions,physical mecha... |
