摘　　要：为探究机场地基处理施工对孔隙水压力的影响,以济南遥墙国际机场工程为依托,通过对强夯区和高速液压夯区分别开展孔隙水压力现场试验,分析了地基在不同夯击能作用下的孔隙水压力增长和消散规律。通过现场监测,研究了不同埋深和夯击能作用下的孔隙水压力变化,揭示了地基处理对孔隙水压力的影响。研究结果表明,夯击能与孔隙水压力增长呈正相关关系,不同夯击能对土层的影响程度不同,地基处理方式对孔隙水压力的消散具有重要影响。该结论可为今后强夯、高速液压夯对孔隙水压力变化研究提供一定的参考。In order to explore the impact of airport foundation treatment construction on pore water pressure,the Jinan Yaoqiang International Airport project is taken as an example.The field tests of pore water pressure were conducted 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 monitoring,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 correlation 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.
