Calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. The upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. In this paper formulation of finite element limit analysis is introduced ...

IN TR O D U C TIO N The fact that the compressive strength of a soil is a function of the time required to reach the failure load has long been recognized. How­ ever, this area of soil mechanics has not been extensively explored and much work remains to be done, in order that the effects of this phenome­ non can be properly evaluated. The specific areas where this information would be of the gr...

Data obtained recently by the Mars Orbiter Laser Altimeter (MOLA) were used to study the statistical properties of the topography and slopes on Mars. We find that the hemispheric dichotomy, manifested as an elevation difference, can be described by long baseline tilts but in places is expressed as steeper slopes. The bimodal hypsometry of elevations on Mars becomes unimodal when referenced to t...

This paper presents the results of a number of computations using the 2D FEM to show the effects of significant variables on the behavior of geosynthetically reinforced earth slopes. The verification and reliability of the results are primarily examined through comparisons with experimental data available. The results seem to be quite acceptable and can be used with a high degree of reliability...

In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...

Abstract In the paper numerical modelling of ensuring slope stability and their analysing with using different methods are presented. We have designed cutting walls earth nails anchors securing for ensuring. The calculate mechanism failure process reinforced slopes were studied stability. nailing significantly increased level Spencer method. Increasing nail or length improved slopes. exhibited ...

Synthetic Aperture Radar Interferometry (InSAR) is an established powerful technique for change detection. Its advantages include competitive spatial resolution, accuracy in milimeter-centimeter scale and spatial coverage. However, there are limitations in using it for detecting the Earth surface changes. Line-of-sight ambiguity (1-D displacement), temporal and geometrical decorrelation (slopes...
