摘要

实验室制备具有典型代表特征的均匀试样是研究天然气水合物沉积物力学特性的前提条件。通过含甲烷水合物砂土（HBS）的三轴剪切试验,首先对比富气法和霜种子法制得HBS试样的力学特性区别,并分析其差异机制;同时,系统性研究霜种子法制备的HBS试样变形和强度特性受水合物饱和度的影响规律。试验结果表明：霜种子法制得试样强度高于富气法制备的试样,主要原因在于富气法制得HBS试样中水合物分布相对不均匀;霜种子法制得试样强度和割线模量随水合物饱和度上升而提高,其内摩擦角基本不受水合物饱和度影响,但黏聚力与水合物饱和度呈现明显的正相关影响趋势。

Abstract

It is a prerequisite to study the mechanical properties of natural gas hydrate-bearing sediments to prepare uniform samples with typical characteristics in the laboratory. In this paper, the mechanical properties of hydrate-bearing sand（HBS） samples prepared by excess gas method and frost seeding method were compared by triaxial shear test of methane HBS, and the mechanism of the difference was analyzed. At the same time, the influence of hydrate saturation on the deformation and strength characteristics of HBS samples prepared by frost seed method was systematically studied. The results show that the strength of samples prepared by frost seeding method is higher than that prepared by excess gas method, primarily due to the relatively uneven distribution of hydrate in the HBS samples prepared by excess gas method. The strength and secant modulus of the samples prepared by frost seeding method increased with the increase of hydrate saturation, and the internal friction Angle of the samples was basically not affected by hydrate saturation, but the cohesion and hydrate saturation showed an obvious positive correlation trend.
