某5层营业楼,框架结构,底层建筑面积720m~2,钢筋混凝土条形基础。建筑场地在老城区,地面以下杂填土约6m深,工程地质报告提供的杂填土层地基承载力无数据,参考邻近建筑物,最高不超过80kPa,且从土工试验数据看,土质松散,密实性极差,不能作为天然地基。经多方案比较,最后确定采用干振碎砖桩处理软弱地基。
A 5-storey business floor, frame structure, the ground floor area of 720m ~ 2, reinforced concrete strip foundation. The construction site is about 6m deep in the old urban area. The bearing capacity of the mixed fill foundation provided by the engineering geological report is no data, the reference to the adjacent buildings is not more than 80kPa, and from the geotechnical test data, the soil is loose, Very poor compactness, not as a natural foundation. The multi-program comparison, and finally determine the use of dry vibration broken brick pile processing of soft ground.
