南海海底土体物理力学特征及其地质环境初步研究

Physical and mechanical characteristics of seabed soils and its geological environment in South China Sea

根据近十多年来多个部门开展的海洋工程地质勘察以及岩土工程测试所获得的资料,对南海不同海区、不同土体类型、不同沉积环境海底土的物理力学性质及其地质环境作了初步研究,总结出滨海区、海峡区、内陆架区、外陆架区、陆坡区、深海平原区不同土体的物理力学特征及其与形成时代、沉积环境、物质组分之关系,为海洋资源开发和工程建设以及海洋区域发展规划提供了重要依据。

The different physical and mechanical properties as well as the various geological environment of the seabed soils deposited on different sedimentary conditions and areas, in South China Sea, have been expatiated in this paper according to the data obtained from marine survey of the dozens of geotechnical engineering companies for many years. It is given the consequence of the relationship between physical and mechanical properties and formation age, sedimentary condition, material composition of the different soils deposited at shore, strait, inner and shelf, slop, deep sea plain. It can provide with important reference for marine exploitation, development and constructions.
