摘要

摘要本文涉及所选各向同性失效准则的特征参数,即莫尔-库仑、德鲁克-普拉格、松冈-中井和拉德-邓肯。参数直接根据失效标准和应力测量值确定,或通过半理论方法确定,假设土壤遵循相关的流动规则并使用平面应变条件。在后一种情况下,参数可以表示为平面应变内摩擦角的函数,该函数由测量值确定。在一系列真三轴平面应变试验中,在不同初始相对密度的Skarpa粗砂样品上,在不同围压下,测量了与土壤峰值强度相对应的主应力张量分量,这些分量是获得破坏准则参数所必需的。

Characteristic parameters of soil failure criteria for plane strain conditions – experimental and semi-theoretical study
Abstract The paper concerns the characteristic parameters of the selected isotropic failure criteria, i.e. Mohr–Coulomb, Drucker–Prager, Matsuoka–Nakai and Lade–Duncan. The parameters are determined directly from the failure criteria and stress measurements or by semi-theoretical approach, assuming that the soil obeys the associated flow rule and using the plane strain condition. In the latter case, the parameters can be expressed as functions of the plane strain internal friction angle, which is determined from measurements. The principal stress tensor components, corresponding to the soil peak strength and necessary to obtain the failure criteria parameters, are measured in a series of true triaxial, plane strain tests, on coarse Skarpa sand samples of different initial relative density, subjected to various confining pressures.

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
