1 蒋村地区地质的基本特征 杭州西部蒋村地区是目前房地产商争相开发的黄金地块。据不完全统计,在该区已建和在建的7层及以下商住楼建筑面积达500万m~2之多。笔者曾搜集了文一路、文三路延伸段与教五路、杭三路之间5个小区占地面积约8万m~2的地质状况。尽管每个小区地质分布有较大的差异,如忽略一些夹层和透镜体,分布还是有一定的规律。该区建筑场地为第四系滨海相沉积地貌,属软土地基类型。地表下主要有6类土层,
1 The basic features of the geology of the Jiangcun area The Jiangcun area in the west of Hangzhou is a prime plot for real estate developers to develop. According to incomplete statistics, the construction area of the commercial and residential buildings of the 7th floor and below that have been built and under construction in the district has reached 5 million m2. The author once collected the geology of the 5 communities between Wenyi Road, Wensan Road Extension Section, Jiaowu Road, and Hangsan Road, with an area of about 80,000 m2. Although there is a large difference in the geological distribution of each plot, if there are some sandwiches and lens bodies, the distribution still has certain rules. The construction site of this area is the Quaternary coastal sedimentary landform, which belongs to the type of soft soil foundation. There are mainly 6 soil layers under the surface.
