Optimization of Dynamic Compaction Treatment Scheme for Collapsible Loess Foundation
This paper used the finite element calculation analysis to optimize the construction parameters of the dynamic compaction treatment for the collapsible loess foundation,and combined with the field test results,the rationality of this method was analyzed.According to the calculation result,the optimal compaction times were 7 times and the compaction energy was 2 000 kN·m.From the test results in the construction field,it was concluded that the bearing capacity of the foundation soil after the dynamic compaction reached the design requirement,and the collapsibility of the loess was eliminated,indicating that the expected reinforcement effect has been achieved.
