基于数值模拟的高填方红黏土地基强夯试验研究OACSTPCD

To minimize the frequency of dynamic compaction passes on high-filled red clay foundations,a large-scale earthwork project currently underway in Yunnan Province is taken as the study case,and the Abaqus numerical software is used to conduct simulations for determining the effective reinforcement range of the foundation across various compaction energy levels.A comprehensive comparative analysis,incorporating construction efficiency and economic factors,is then performed to identify the optimal energy level for dynamic compaction of the red clay filled foundation.Field compaction tests are subsequently carried out,guided by the energy levels and reinforcement ranges obtained from the numerical simulations.Additionally,techniques such as plate loading and dynamic probing are utilized to assess the red clay filled foundation after dynamic compaction.The results from these tests confirm that the post-compaction foundation meets the strength and deformation requirements specified by the main structural design.These research findings provide invaluable guidance for addressing challenges associated with high-filled red clay foundations.
