Analysis on Dynamic Compaction Design and Field Test of Large-scale Excavation and Filling Foundation
Dynamic compaction is one of the economical and effective methods for foundation reinforcement in mountainous projects.In order to ensure the construction quality of a large-scale peak cutting and valley filling site leveling project in Guizhou's mountainous area,this paper conducts the construction parameter design and field test detection analysis of dynamic compaction replacement and dynamic compaction reinforcement.On the basis of systematically carrying out the design of construction parameters such as tamping energy,tamper size,drop distance,tamping point spacing,tamping times,final two tamping settlement and interval time,the tamping effect is verified by dynamic penetration test,foundation static load test,field compactness and other foundation detection tests,and the applicable construction parameters of the project are determined,which can provide reference for similar projects.
