3D Finite Element Analysis of Diaphragm Wall Construction Stages in Sand

August 01, 2019

Construction of underground structures may impose a hazardous effect on adjacent buildings due to ground movements caused by the construction of side support system and excavation. Most studies focus on predicting the soil movements due to excavation, however, limited research is performed to predict the effect of the construction process of the side su...

Geomembrane as an Upstream Impermeable Blanket of Embankment Dams - Laboratory and Numerical Study

December 13, 2018

The use of geosynthetics has been a common practice in geotechnical engineering when the improvement of local soil characteristics is necessary. This paper presents an experimental and numerical study of the performance of HDPE geomembrane as impermeable blanket installed upstream of embankment dams, a treatment technique for very permeable foundation. ...

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...
