Shear Strength of Soil
One of the most important and the most controversial engineering properties of soil is its shear strength or ability to resist sliding along internal surfaces within a mass. The stability of a cut, the slope of an earth dam, the foundations of structures, the natural slopes of hillsides and other structures built on soil depend upon the shearing resistance offered by the soil along the probable...
متن کاملTheoretical Undrained Shear Behaviour of Unsaturated Soils
Prediction method for undrained shear behaviour of unsaturated soils is discussed in this paper. Based on Original Cam Clay model, authors have proposed constitutive model for unsaturated soils that the effect of water content is incorporated into superloading surface concept. Firstly, stress path of constant volume shear test is formulated under constant void ratio condition. And relationship ...
متن کاملArtificial Neural Network Approach Based Indirect Estimation of Shear Strength Parameters of Soil
The shear strength parameters of soil such as cohesion (C) and angle of internal friction (φ )govern the bearing capacity of shallow or deep foundations, the stability of the hill slopes as well as slopes of dams and embankments, design of retaining structures etc. in most of the civil engineering practices. In this study, artificial neural network (ANN) with the feed-forward back-propagation a...
متن کاملMultivariate Adaptive Regression Spline and Least Square Support Vector Machine for Prediction of Undrained Shear Strength of Clay
This study adopts Multivariate Adaptive Regression Spline (MARS) and Least Square Support Vector Machine (LSSVM) for prediction of undrained shear strength (su ) of clay, based Cone Penetration Test (CPT) data. Corrected cone resistance (qt ), vertical total stress (σv ), hydrostatic pore pressure (u0 ), pore water pressure at the cone tip (u1 ), and pore water pressure just above the cone base...
متن کاملestimation surface soil shear strength by pedo-transfer functions and soil spatial prediction functions
abstract surface soil shear strength is an effective parameter in soil erosion and runoff modeling, and known as soil erodibility index. this study was conducted to investigate and predict soil shear strength in central zagros region using multiple linear regressions (mlr). the study site was selected in rangeland and degraded-rangeland landuse with an area of 23562 ha. based on the maps of geo...
