摘要
介绍了振动碎石桩处理机场跑道地基的效果。根据钻探取样和原位测试结果,分析了碎石桩处理前后的孔隙水压力变化情况,并对比了处理前后的土层物理力学性质指标,分析了砂土地震液化可能性,得出了检测结论,可供类似工程参考。
Treatment effects of the airport runway foundation reinforced with vibrc-compation gravel pile are discussed, Bseed on data of drilling sampling tests and in situ tests, the variation rules of pore water pressure before and after the treatment are analyzed. Physical and mechanic property indexes of soil before and after the treatment are compared, and probability of sand seismic liquefaction are proposed. Some conclusions are given, which can provide reference for other engineering.
