【摘要】 本文对大连保税区填海区深填道路路基的强夯加固现场进行了试验和检测,通过对试夯区试夯,得出了强夯法的施工参数。现场检测结果表明,采用2000kN.m的夯击能使回填碎石土路基的有效加固深度达到7m左右,强夯后路基的各项力学指标都有明显的提高,满足设计要求。该场区强夯加固的成功,为深填海区及类似工程的设计施工提供借鉴。更多还原

【Abstract】 The tests and inspection are carried out for the high filling subgrade treated by dynamic compaction in land accretion area of Dalian Free Trade Zone.Through the testing compaction the construction parameters for dynamic compaction method are obtained.The field inspection data for the strengthened foundation shows that the effective depth of the influence is about 7m by the compaction energy 2000kN·m,the bearing capacity is increased and the degree of compaction can meet the design requirements after dynamic compaction.Based on the in-situ testing data,some available conclusions are obtained,which can provide the scientific basis for the similar engineering.更多还原
