摘要
天然原状黄土由于自身颗粒之间的大孔隙和颗粒间相互胶结,从而具有显著的结构性。结构性及其变化显著影响土的力学特性及其稳定性。在诸如边坡、隧道、路基、基坑等平面应变问题的实际工程中所采用的理论大多是基于重塑土建立的,并没有考虑土的结构性。通过分析原状黄土的工程特性,定量化研究结构性黄土和重塑黄土之间的力学行为差异,建立土体强度变形稳定分析理论,完善土力学体系,指导工程实践。
Due to its natural loess large gap between the particles and particles cemented with each other,and thus have a significant structural o Structural changes significantly influence their mechanical properties and stability of soilo Such as slope, tunnel, embankment, excavation and other problems of practical engineering plane strain used in the theory are mostly based on established remolded, it does not take into account the soil＇s structural. This paper analyzes the engineering properties of loess, Quantitative study of the structural remodeling of loess and loess difference between the mechanical behavior, establish the soil strength and stability analysis of the deformation theory, Improve the system of soil mechanics, guidance the engineering practice o
