Abstract
The DDC pile(Deep Dynamic Compaction method)is a deep foundation treatment technique that has been successfully applied in petroleum and petrochemical engineering,building construction,and road engineering,but has not yet been widely adopted for super-heavy load structures in coal-fired power plants.This paper selects the large steel ash silo of a coal-fired power plant in north China as the research object.This structure bears heavy loads and has strict requirements for foundation strength and deformation.The characteristic value of bearing capacity of the composite foundation is determined based on static load test results.The foundation settlement is calculated using the layered summation method.Through theoretical calculations and on-site testing,key technical indicators of the DDC pile composite foundation,including bearing capacity and compression modulus,all meet the design requirements.The DDC pile has performed well in this area,providing additional options for foundation treatment of large steel ash silo.关键词
