摘　　要：渤海湾西岸滩海地区沉积层的物理力学性质除受到随深度压缩固结的影响外,还取决于形成时的沉积环境。滩海地区浅部沉积由海相、陆相层交替叠覆而成。陆相层致密硬塑,含水量低,湿重度大,压缩性小,具有较高的承载能力。海相层含水量高,湿重度小,压缩性大,承载力低。The property of physical-mechanics about deposit of sea beach area of west coast of the Bohai bay is restricted by the influence of compress with depth, and depends on the deposit environment. Continental and marine deposits compose the shallow deposit of sea beach area in turn. The stratum of continental deposit is compact and solid, small moisture content, big density, small compress and high bearing capacity. The stratum of marine deposit is high moisture content, small density, high compress and small bearing capacity. The engineering installations in this area come across many problems of engineering geology. Understanding the deposit environment of shallow stratum is the premise of explaining the phenomenon of engineering geology correctly and improving technique for industrial installation in the sea beach area.
