Abstract: The paper describes the results of marine engieering geology research incoastal zones, estuarine deltas, harbour constructions,offshore oil exploitation and technigres method. The study shous the present situation of marine engineering geology theories in China, microstructures of marine sediments, soil dynamic properties, prediction of liguefaction under ocean wave loading and stability treatment of undersea soft soil. The development trend of the discipline and some suggestions on further marine engineering geology research are put forward in this paper.
