%X With seismic exploration extending to liquid-covered areas(such as shallow sea and lakes), much attention is being paid to the propagation of the guided wave in media underlying a liquid layer or with interlayers. Based on previous researches, we calculate the dispersion curves respectively for two-layer, three-layer and a low-speed-inter layer models, which are covered with a liquid layer. We analyze the different characteristics of the multi-made guided wave, for varied thickness of the liquid layer. We compare the geometric characteristics of the multi-mode-dispersion curves to those of that without a liquid surface. And then, we point out some problems which should be taken into consideration when seismic exploration is applied in off-shore areas. The study in this paper may provide some thoughts and theoretical bases for guided wave exploration in liquid-covered areas.
