foundation is replaced by dynamic compaction with backfilling block stone, gravel or other coarse granular materials in the compaction pit, its applicability should be determined by field tests.强夯施工前，应在施工现场有代表性的场地上选取一个或几个试验区，进行试夯或试验性施工。试验区数量应根据建筑场地复杂程度、建设规模及建筑类型确定。
Before dynamic compaction construction, one or more test areas should be selected on the representative site of the construction site for trial compaction or experimental construction. The number of test areas should be determined according to the complexity of construction sites, construction scale and type of buildings.
