While these differences can be appreciable for some geotechnical problems, the practical implications of neglecting interfacial forces in effective stress formulations for the mechanical behavior of unsaturated
土力学有效应力之雨天防滑 [Effective Stress of Soil] 实干、实践、积累、思考、创新。 土力学有效应力之雨天防滑 崔济东 (Jidong Cui);沈雪龙 ( Xuelong Shen ). 有效应力原理是土力学区别于其他力学的一个重要原理,由太沙基(K. Terzaghi)提出,并经Skempton和Bishop改进而被广泛接受。该原理认为饱和土中的压应...
1.1.12 Effective stress for deformation Several definitions exist for effective stress. Depending on applications, a suitable effective stress definition must be used. However, if it is applied to analyze structure stability problems, the Terzhagi’s effective stress concept is the most convenient for...
Dynamic effective stress response of soil structures: theory and centrifuge model studies : Finn, W D L Proc 5th Itnernational Conference on Numerical Methods in Geomechanics, Nagoya, 1–5 April 1985 V1, P35–46. Publ Rotterdam: A. A. Balkema, 1985...
The effective stress parameters of a soil sample can be obtained from both consolidated undrained test and consolidated drained test. However, consolidated undrained test is normally selected because of the following reasons: (i) Time taken for...
The effect of spatial variability on the effective Young''s modulus of a soil mass is investigated. The soil mass is a two-dimensional plane strain square domain subjected to a simple stress state, with Young''s modulus being modelled as a stationary lognormal random field. The effective ...
Effect of Confining Stress on Soil Water Retention Curve and its Impact on the Shear Strength of Unsaturated Soils To predict the shear strength of unsaturated soils, several equations have been proposed in the literature. The majority of these equations have the air en... MH Tavakoli Dastjerdi...
To answer the research questions, a case study is con- ducted in southern Italy, a region historically and increas- ingly concerned by water stress, interviewing stakeholders along the water reuse value chain related to a water utility and its reclamation facilities. The study takes the central ...
