兰州乳品厂工程位于原段家滩养鱼池西段人工回填的建筑与生活垃圾土上。经强夯法处理地基,取得了良好的技术经济效果,现将应用情况简述如下。一、工程地质情况厂址位于黄河南岸二级阶地上,经人工填筑推平。上部为4.5～5.7米厚度不等的人工填筑土层,以工业建筑垃圾为主,含有较多的炉渣、破碎混凝土预制板、砖石块,还有布条、铁丝、木块、纸屑和杂草等生活垃圾。此层土结构松散,天然地基承载力低,[R]值为3.75吨力/米~2。浸水附加沉陷量较大,实测在10吨力/米~2压力下的浸水附加沉
The Lanzhou Dairy Factory Project is located on the backfilled building and domestic garbage soil in the west section of Duanjiatan Fish Farm. After the treatment of the foundations by the strong ramming method, good technical and economic results have been achieved. The application is briefly described as follows. 1. The site of engineering geology The site of the project is located on the second terrace of the South Bank of the Yellow River, and is manually filled and flattened. The upper part is 4.5 to 5.7 meters of artificially filled soil layers of varying thickness, mainly consisting of industrial construction waste, containing more slag, broken concrete prefabricated panels, bricks and stones, as well as cloth strips, wire, wooden blocks, paper scraps And weeds and other domestic garbage. This layer of soil structure is loose, the natural foundation bearing capacity is low, [R] value of 3.75 tons force / m ~ 2. The submerged subsidence is larger and the submerged submerg
