This article describes the use of GPR in urban slopes stability analysis. The studied slopes, located at Belo Horizonte County, Brazil, were named Planetóides and Rio Acima and, respectively, are composed by talus over phyllites and talus over schist. Successive landslides have been occurred in these sites during rainy season. At Planetóides slope was possible to observe the talus depth and the presence of more than two circular landslide surface scars. At Rio Acima slope the geophysics profile made possible to observe the depth, orientation and intensity of the schistosity and fractures. These discontinuities are responsible for planar failures of the rock mass. The results of the GPR analysis together with other geotechnical studies made possible the detection of the main parameters used during stability analysis and helped in establishment of the failure mechanisms that had occurred in these slopes.

This paper presents a model for deterioration and repair of a railway line. The critical failure is "broken line". Two main failure mechanisms are considered: either shock failure, i.e. an immediate critical failure (without "warning"), or the critical failure occurs as the result of a degradation process, i.e. a degraded failure (crack) occurs first. Various types of inspection and maintenance

Landslides at continental margins are natural hazards for submarine installations and coastal regions. The occurrence of gas hydrates at continental margins is thought to be one major cause for these slides. It is assumed that the decomposition of gas hydrates increases the water content of the host sediment and thus lowers the strength of the soil. In order to predict

This note shows a study on the seismic passive earth pressure behind a non-vertical cantilever retaining wall using pseudo-dynamic approach. A composite failure surface comprising of an arc of the logarithmic spiral near the wall and a straight line in the planar shear zone near the ground, has been considered behind the retaining wall. The effects of soil friction angle, wall inclination, wall friction angle, amplification of vibration, horizontal and vertical earthquake acceleration on the passive earth pressure have been explored in this study. The results available in the literature for passive pressure, on the basis of pseudo-static analysis are found to predict the passive resistance on the conservative side and the assumption of a planar failure surface is found to overestimate the passive resistance for higher wall friction. An attempt has been made in the present study to overcome both the limitations simultaneously. The present results are compared with the existing values in the literature and found a reasonable match among the values.
