陆上天坑与海底麻坑对比研究

摘要

The historical records showed that the Tiankeng and seabed Pockmark were basically respectively studied in the past, and there were few comprehensive comparative studies on the Tiankeng and seabed Pockmark. Through the comparison and research of geological background, dynamic mechanism, geometric shape, evolution and activity of Tiankeng and seabed Pockmark, their similarities and differences were analyzed, which could provide some reference for studying the negative terrain type collapse of land and sea, and could provide supports for marine engineering construction .%从历史文献记载上看,陆上天坑与海底麻坑基本上是分别研究,少有两者综合比较研究.本文通过对陆上天坑与海底麻坑的地质背景、动力机理、几何形态、发育演化以及活动性等进行对比研究,分析其相同点与不同点,旨在为陆上和海底塌陷型负地形研究提供一些参考,为陆上大型基建工程及海洋工程建设提供地质支持.
