摘　　要：藏东南地区河谷地带具有深厚的砂卵石地层,砂卵石的优点是抗剪强度高,水稳定性好,但是缺点是不易击实。因为藏东南地区具有深厚的砂卵石地层,在其上进行各项工程建设时,采取强夯法进行地基处理,可以达到工程建设对地基承载力的需求。从理论出发,结合藏东南深厚砂卵石实际情况,得出了强夯法应用于藏东南地区砂卵石地基的施工方法。通过实际工程的检验,强夯法能应用于藏东南地区深厚砂卵石地基的加固,有效保证其地基的承载力。The thick and loose sandy gravel and pebble soils are widely deposited in the river and valley region of southeast Tibet.The gravel and pebble soils have a high shear strength and good water stability,but they are difficult to compact.Based on the experience of various dynamic projects performed on the thick deposited gravel and pebble soils,it is concluded that the dynamic compaction method can improve the bearing capacity characteristics and meeting the project requirements.Dynamic compaction method is proved to be a well-established and cost-effective method for various engineering projects.
