Application study of SDDC method in improving thick layer artificial backfill soil
This paper introduces the basic principle of SDDC method,applies it to the treatment of thick layer artificial backfill soil in an airport,and the inorganic solid waste is recovered and utilized as resources.The construction quality of SDDC is tested by loading test,standard penetration test and heavy dynamic sounding test.The bearing capacity of SDDC pile and soil between piles are evaluated and analyzed.The results show that the uniformity of composite foundation treated by SDDC method is good.The bearing capacity of foundation has significantly improved and meets the engineering requirements.
