ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...

The evaluation of seismic slope performance during earthquakes is important, because the failure of slope (such as an earth dam, natural slope, or constructed earth embankment) can result in significant financial losses and human. It is important, therefore, to be able to forecast such displacements induced by earthquake. However, the traditional forecasting methods, such as empirical formulae,...

Automatic estimation of velocities from GPS coordinate time series is becoming required to cope with the exponentially increasing flood of available data, but problems detectable to the human eye are often overlooked. This motivates us to find an automatic and accurate estimator of trend that is resistant to common problems such as step discontinuities, outliers, seasonality, skewness, and hete...

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...

The range of 3 ø by 3 ø regional slopes of the earth and Venus is similar (approximately 0.0ø-2.4ø); however, the surface distribution of these values differs significantly. On earth, cratonic and abyssal plains form extensive regions of 0.0 ø slope. Within these regions a variety of features (mid-ocean ridges, volcanic island chains, subduction zones, and folded mountains) have regional slope ...

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...
