1. Research results suggest that many instabilities exist in tidal channels of ⅱ and ⅲ 2 regions, what is more, the deep troughs of the channel, concave bank, conjoining of channels and margins of relict salients in channels are the positions where the instabilities concentrate.
研究结果表明土体失稳主要分布于、2区的潮汐通道中，且以通道深槽边坡、通道凹岸、通道交汇处以及通道中的残留高地边缘等部位最为常见。
