强夯及液压夯作用下孔隙水压力影响研究
Study on Impact of Pore Water Pressure Under Dynamic Compaction and Hydraulic Compaction
摘要
Abstract
In order to explore the impact of airport foundation treatment construction on pore water pressure,the Ji-nan Yaoqiang International Airport project is taken as an example.The field tests of pore water pressure were con-ducted in the dynamic compaction area and the high-speed hydraulic compaction area respectively,and the growth and dissipation laws in the foundation under different compaction energies were analyzed.Through on-site monitor-ing,the variation of pore water pressure under different burial depths and compaction energy were studied to reveal the impact of foundation treatment on pore water pressure.The research results indicate that there is a positive cor-relation between compaction energy and the increase of pore water pressure.Different compaction energies impact differently on soil layers.The foundation treatment method has an important impact on the dissipation of pore water pressure.The conclusions can provide some reference for future research on the variation of pore water pressure caused by dynamic compaction and high-speed hydraulic compaction.关键词
