摘要

摘要本文主要研究了岩石和土体沿干、湿表面滑动时的抗剪强度,这种破坏机制与水润滑现象密切相关。众所周知,岩土材料的摩擦行为需要多尺度的研究。在此视角下,利用文献数据分析了颗粒尺度上的摩擦(即颗粒间摩擦)和岩石和颗粒土样品沿滑动表面的摩擦(即表面摩擦)的实验证据。这篇综述是在不同的尺度上进行的,说明了岩石和土壤在滑动摩擦响应方面的差异,并试图指出研究中仍然存在的问题。

Does water lubrication affect friction differently for rocks and soils? Evidence and open questions
Abstract The present paper focuses on the shear strength exhibited by rocks and soils when sliding along dry and wet surfaces, with this mechanism of failure being strongly related to the water lubrication phenomenon. It is well known that the frictional behaviour of geomaterials requires multiscale investigation. Under this perspective, experimental evidence of both friction at the grain scale (i.e. interparticle friction) and friction along sliding surfaces of rock and granular soil samples (i.e. surface friction) are analysed by using data from the literature. The review is addressed at linking different scales, stating the differences between rocks and soils in terms of frictional response to sliding and trying to point out still open problems for the research.

期刊介绍: An international journal ‘Studia Geotechnica et Mechanica’ covers new developments in the broad areas of geomechanics as well as structural mechanics. The journal welcomes contributions dealing with original theoretical, numerical as well as experimental work. The following topics are of special interest: Constitutive relations for geomaterials (soils, rocks, concrete, etc.) Modeling of mechanical behaviour of heterogeneous materials at different scales Analysis of coupled thermo-hydro-chemo-mechanical problems Modeling of instabilities and localized deformation Experimental investigations of material properties at different scales Numerical algorithms: formulation and performance Application of numerical techniques to analysis of problems involving foundations, underground structures, slopes and embankment Risk and reliability analysis Analysis of concrete and masonry structures Modeling of case histories
