Abstract:
In order to improve dynamic compaction effect and construction efficiency,the space and number of tamping are optimized through reinforcement of a substation foundation in Guangxi.The optimal space of tamping and condition for stop hammering under the formation condition of this substation are summarized and the process of dynamic compaction is discussed in this paper.
