This paper presents a new approach of landslides zonation hazard studies, based on an integrated study of structural data along with geomorphological and external factors, in a hilly regions of Brazil, covered by a tropical humid rain-forest, called Serra do Mar. The Serra do Mar consists of a hilly region along the east coast of Brazil, with high slopes and many geological structures in a gnei...

Flexural toppling failure is a common mode of natural and artificial rock slopes, which has caused serious damage to human life property. In this work, an advanced numerical method called the Universal Distinct Element Code (UDEC) was used study mechanism flexural failure. total, more than twenty slope models were built analyzed. Two new parameters (displacement discontinuity transition coeffic...

Flexural toppling is typically observed in anti-dip bedding rock slopes with a set of steeply dipping parallel joints against the slope face. This failure occurs due to bending strata, similar cantilever beams. However, exact surface usually unknown, which leads an assumption regarding location and shape that must be made theoretical analysis. serves as basis for stability analysis but may lead...

The rock slope stability analysis can be performed using deterministic and probabilistic approaches. based on the safety concept factor uses fixed representative values for each input parameter involved without considering variability uncertainty of mass properties. Probabilistic with calculation probability failure instead against is emerging in practice. Such analyses offer a more rational ap...
