分析了强夯法加固地基时,夯击能、夯点距离、夯击数等因素对周围已建建筑物的安全的影响。通过振动速度、振动加速度、地基位移、建筑物的变形等项目的监测来确定强夯的安全距离。结果表明,强夯对建筑物影响分析采用地震烈度对建筑物危害标准进行评价是比较合适的。

Analyses were made of the influence of tamping energy, distance of tamping points and number of passes upon the safety of the existing surrounding structures when a foundation is improved with the dynamic compaction method. The safe distance of dynamic compaction to the exiting structures was determined according to the measure- ments of vibrating speed, vibrating acceleration, foundation displacement and deformation of structures. The results of the analyses indicate that it is more adequate to evaluate the influence of dynamic compaction upon buildings with the standard of earthquake intensity jeopardizing buildings.
