摘要:
我国西北内陆和东南沿海含盐土地区的大规模基础设施建设,促进了含盐冻土物理力学研究的发展。从含盐冻土的强度特征、冻融变形特性、水盐迁移规律以及细微观结构研究等4个方面,简要概述了国内外研究现状,总结了含盐冻土物理力学特性的研究进展。提出人工含盐冻土强度和变形特性研究中需增大试验负温范围,以获得氯化钠二次相变对冻土强度和冻融变形的影响规律; 从冻融过程中未冻水含量、土水势、孔隙水压力和盐晶体相变等关键机制入手,研究含盐冻土的变形机理; 指出现有测定水分、盐分、基质势和孔隙水压力等传感器不能满足室内试验对尺寸和精度的要求,采用微型化、精确化的传感器进行冻融过程中的水盐迁移参数监测,是建立合理的水-热-力-盐耦合模型的前提; 提出可将未冻水含量作为微观尺度的孔径分布与宏观强度特性和水盐迁移模型联系的纽带,为建立微观与宏观的联系提供一种新思路。
Abstract:
The massive infrastructure construction in the northwest inland and southeast coastal saline soil areas of China promotes the development in physical and mechanical researches of frozen saline soils.This review summaries the research status at home and abroad from four aspects of frozen saline soils such as strength, freeze-thaw deformation, water-salt migration law, as well as the variation of soil mesostructure and microstructure.The research tendency is put forward as follows based on the review of references.The negative testing temperature range of experiments is required to expand, in order to investigate the effects of the secondary phase change on strength characteristics and freeze-thaw deformation mechanism of frozen saline soils.It is lack of the investigation on the influence of the secondary phase change of sodium chloride on soil physical and mechanical properties.In addition, this review points out that the deformation mechanism of frozen saline soils during the freezing and thawing can be studied on the following four parameters, including unfrozen water content, matric potential, pore water pressure, and the amount of salt crystallization and dissolution.However, the available sensors cannot meet the requirements of size and accuracy in laboratory tests to obtain the values of the mentioned parameters.For the reason that the size of sensors is usually large and the accuracy of them is not high enough.Therefore, the application of the miniaturized and high-accuracy sensors for monitoring the parameters during the freezing and thawing is a prerequisite for establishing a reasonable thermos-hydro-salt-mechanical coupled model.A novel idea is also proposed in this review that unfrozen water content can be taken as a connection to build the relationship between microscopic and macroscopic aspects.To be specific, unfrozen water content is related to the micro pore size distribution and is an important parameter of researches on strength characteristics and water-salt migration of frozen saline soils.
