摘要:
首次通过物理模拟手段对黄土地层中的突涌破坏现象进行了研究,深刻揭示了突涌变形破坏特征及其影响因素,指出突涌变形破坏特征主要取决于黄土试样的均质性、初始密度、初始含水量、水压及边界条件及其变化变化。试验结果同时表明,黄土试样的均质性、初始密度、初始含水量、水压及边界条件对初始流网形态起着控制性作用,这不仅是突涌变形破坏特征有所差异的根本原因之一,同时也是决定突涌变形破坏后续侵蚀特征的主要因素。本文研究从多个角度全面揭示了突涌的发生机理,其结论为黄土潜蚀机理的相关研究提供了有力借鉴。
Abstract:
Abstract: By means of physical simulation, the phenomena of soil-bursting in loess were studied for the first time. The results revealed the deformation characteristics and factors of soil-bursting. The authors concluded that the deformation and failure characteristics depend on the heterogeneity of the loess samples as well as the initial density, initial moisture content, pressure head, boundary condition and its changes. The results also showed that the heterogeneity of the loess samples as well as the initial density, initial moisture content, pressure head, boundary condition and its changes play a controlling role in the formation of the initial drift-net shape, which finally led to the different erosion characteristics of deformation and soil-bursting failure. This paper comprehensively revealed the mechanism of soil-bursting, and its relevant results provided a reference for the further mechanism research of sub-ground erosion in loess.
