菲律宾马尼拉湾海洋土物理力学性质分析

Physical and Mechanical Properties of Marine Soil in Manila Bay,Philippines

菲律宾马尼拉湾某海域勘察深度范围内广泛分布褐黄、暗绿色高液限黏土层,这类土具有含水率高、孔隙比大、剪切强度大、压缩性偏低的特性,与国内陆地土和东海近岸海洋土的性质有很大的不同,本文通过对这类土的物理力学性质指标的测试、分析,并研究其地质成因、物质组成和胶结作用等内在因素,加深对海洋土的工程特性认识,为全面了解和评价这类土的工程地质特性提供定性和定量的依据。

The brownish-yellow and dark-green high-liquid-limited clay layers are widely distributed in a sea area of Manila Bay in the Philippines.This type of soil has the characteristics of high water content,large porosity,high shear strength and low compressibility,which is very different from the nature of the offshore soil in the East China Sea.In this paper,through the testing and analysis of the physical and mechanical properties of this type of soil,and the study of its internal factors such as geological genesis,material composition and cementation,so as to deepen understanding of engineering characteristics and provide a qualitative and quantitative basis for a comprehensive understanding and evaluation of the engineering geological characteristics of this type of soil.
