【摘要】 大面积的多孔隙、粗颗粒非饱和土地基的加固处理宜采用强夯法。加固深厚地基,特别是大孔隙湿陷性地基、山区大厚度非均匀块石回填地基和抛石填海地基,应该施加高能级强夯进行处理。我国的高能级强夯主要用于石化工程施工中的生产装置和大型储罐地基。结合青岛重交沥青有限公司4座5万m3原油储罐和配套附属设施地基处理工程,对高能级强夯的关键技术、检测方法和综合评价进行了阐述,可供强夯设计施工参考。更多还原

【Abstract】 In order to improve the deep ground, especially heterogeneous block ground of mountain area and rock filling out the sea, high energy level dynamic compaction (HELDC) is necessary to strengthen the ground. The HELDC is mainly used in the production facilities and high-capacity oil tank of petrochemical project, so as to eliminate the collapsibility of loess and treat the non-uniformly stone backfill foundation of mountain area and coast. The succeed experiences of ground treatment using HELDC of 4 oil tanks (50 000 m3) foundation in Qingdao Zhongjiao Asphalt Co. Ltd are described in detail. Finally, some referable conclusions are obtained.更多还原
