Abstract:In order to supplement the existing geotechnical engineering testing technology,for indoor geotechnical engineering impact test and in-situ dynamic plate load testing,a test device and a test method for high-energy electromagnetic force impact of intelligent control were developed,and applied to residual force study in soft ground treatment with static-dynamic drainage consolidation(SDDC). Under the complex stress conditions with SDDC,the residual force test results showed that:(1) The high-energy impact test was carried out very well with the multi-level electromagnetic impact instrument,and the impact force on the impacted object is the object quality 2 000 times more. (2) Under a certain impact load and soil storage conditions,the phenomenon of residual force in soil does exist. (3) The residual stress in soil is mainly related to soil structure and structural changes,and has a certain relationship with the consolidation process in SDDC.
