【摘要】 以某深厚湿陷性黄土地基处理工程为背景,按强夯处理的技术要求,确定了该工程强夯施工参数及施工步骤。通过室内土工试验、标准贯入度试验及载荷试验等方法检验了该地基强夯处理效果。研究表明:该工程地基采用强夯处理后,加固效果明显,地基承载力大幅提高,类似工程施工前可采用修正Menard公式估算强夯有效加固深度。更多还原

【Abstract】 Take the background of one deep collapsible loess foundation reinforcement by dynamic compaction,According to the technical requirements;it defines the parameters and steps of the dynamic compaction construction.According to the results of geotechnical test,standard penetration test and static load test,it examined the reinforcement effect of dynamic compaction.The research results show that: the reinforcement effect obviously when the deep collapsible loess foundation reinforcement by dynamic compaction,and the ground bearing capacity rise higher,and the effective reinforcement depth can computed by correction Menard formula before the similar project construction.更多还原
