南海珠江口盆地工程地质进行了两级分区,一级区反映区域工程地质条件基本特征,二级区反映区内工程地质条件复杂程度。通过区域工程地质特征分析与评价,确认大陆架区比大陆坡区工程地质条件好,其中以中陆架混合土亚区工程地质条件好,外陆架粗粒土亚区工程地质条件较好,上陆坡软土亚区工程地质条件差,内陆架细粒土亚区和上陆坡岩石礁石亚区工程地质条件较差。本项研究成果为南海海洋开发、总体规划和决策提供了依据,也望能促进海洋工程地质科学的发展。
The engineering geology of the Pearl River Mouth Basin in the South China Sea is divided into two levels. The first level reflects the basic characteristics of regional engineering geological conditions and the second level reflects the complexity of engineering geological conditions in the area. Through the analysis and evaluation of regional engineering geological features, it is confirmed that the continental shelf area is better than the continental slope in geological engineering conditions, of which the engineering geological conditions are good in the sub-area of the mixed continental soil shelf, the geological and geological conditions of the coarse-grained soil area in the continental shelf are good, The geological conditions of Tuya area are poor, and the geological conditions of intra-continental shelf fine-grained Tuya area and upper-slope rock reef sub-region are poor. The results of this study provide the basis for the development, master planning and decision-making of the South China Sea in the oceans and seas, and are also expected to promote the development of marine engineering geology.
