| 摘 要： | 黄土地层受含水量和饱和度的影响,以地下水位为界,自然形成黄土二元结构地层.文中以西安黄土地层上、下元结构为例,通过室内三轴试验,分析了上、下元黄土的力学特性.在此基础上,提出黄土地层上、下元结构的变形可采用宾哈姆体模型和Biot固结理论进行耦合分析,并将此运用在西安地铁盾构施工分析中.

| Abstract: | Affected by the water content and saturation degree,the dualistic structure of loess is formed naturally around sub-water.Through taking dualistic structure of collapsed loess in Xi'an as an example and indoor 3-axis experiments,the physical and mechanical properties of dualistic collapsed loess are analyzed.It is proposed that the deformation in dualistic loess structure can be coordinately investigated by using Bingham body model and Biot consolidation theory, and this method is also applied in the analysis of shielding construction in Xi'an metro. |
