沉积作用下海底滑坡失稳触发机制的研究
Journal: Geological and Mineral Surveying and Mapping DOI: 10.12238/gmsm.v7i2.1652
Abstract
海底滑坡位于深海复杂动力环境中,其触发机制较陆域滑坡复杂许多,其中沉积作用作为主要触发机制之一,研究进展及成果却没有地震、波浪、天然气水合物分解等其他因素丰富。因此,本文首先通过总结海底滑坡失稳诱发因素引出了沉积作用较于其他触发因素的特殊之处,进而基于其作为海底滑坡最基本触发因素的认识,梳理概括了在其本身特征和其他因素影响下导致海底滑坡产生的三类沉积作用,最后对三类沉积作用的海底滑坡触发机制及最新研究成果进行探讨与回顾,指出目前研究存在的不足和未来发展方向,以期为揭示沉积作用下海底滑坡失稳触发机制提供重要参考。
