摘　　要：在某工程强夯试验阶段进行了地面振动监测,分析地表振速随夯击次数、夯点距离的变化规律,并参照国家有关标准进行试夯区安全评价。同时,采用非线性回归分析,拟合地表振速与安全距离的负指数函数公式,预估出该工程强夯施工的安全距离,为安全施工创造了条件。By the field monitoring,the regulation of surface vibration varies with tamping number and tamping points distance is analyzed during the test of dynamic compaction construction for a project.And the safety of trial ramming area is evaluated with reference to the relevant national standards.At the same time,the negative exponential function of the surface vibration speed and safe distance is fitted by nonlinear regression analysis.The safe distance of dynamic compaction construction for the project is estimated which creating the conditions for the safe construction.
