摘　　要：介绍面波法检测原理及其在软土地基和软弱夹层测定中的应用.分析表明,根据面波实测波速值可以区分软土或非软土地层;若层间存在较明显的波速度差,而且土层厚度较大时,可以结合一定数量的钻孔,根据波速变化进行分层,获得比较连续的地层剖面,从而减少钻探工作量.An introduction is given to the detecting principle of the surface wave method and its application to survey of soft foundations and weak strata. Analysis shows that the soft and nonsoft strata can be distinguished according to the measured velocity of surface waves. If obvious differences exist between the wave velocities in different strata, and the thickness of the strata is large, by a certain number of holes bored, the soft foundation can be stratified based on the variation of wave velocity, and continuous stratum profiles be obtained, so the method can reduce the work load of boring.
