Shear Creep Properties of Weak Interlayer in Slope Based on Stationary Parameter Fractional Derivative Burgers Model

November 06, 2019

Based on special engineering geological conditions of a cut-slope area at Heitanping hilly-pass along Yongzhou – Jishou highway, shear creep properties of weak interlayer in this slope (about 30 m deep) have been studied by shear creep test to obtain shear creep curves. Shear creep constitutive model can be obtained by stationary parameter fra...

Predicting the Shear Strength of Unfilled Rock Joints with the First-Order Takagi-Sugeno Fuzzy Approach

February 21, 2019
As a result of a number of studies, some analytical models have been developed to predict the shear behavior of unfilled rock joints, but they all present a purely deterministic nature because their input variables are defined without considering the uncertainties inherent in the formation processes of the rock masses and related discontinuities. This work aims ...

Analysis of the Physical-Mechanical Behavior of Clayey Sand Soil Improved with Coir Fiber

December 13, 2018
The objective of this paper is to analyze the mechanical behavior of a clayey sand soil with added green coir fiber at 0.25%, 0.5%, 0.75%, and 1% by dry weight, through a series of laboratory tests that physically and mechanically characterize the samples in order to evaluate possible changes in the soil properties. Unconfined compression and indirect tensile te...

Obtaining the Mechanical Parameters for the Hardening Soil Model of Tropical Soils in the City of Brasília

April 04, 2019
In this article, the mechanical parameters of characteristic soils of the city of Brasília are obtained, calibrated and validated for the Hardening Soil (HS) model, based on laboratory and field test results obtained in previous research studies conducted in the Experimental Field of the University of Brasília (CEGUnB). The strength and compressibi...
