By means of statistical analysis of the data, good correlations between slope failure rate, maximum 24-hour rainfall and slope information have been established for soil cut slopes for a pilot study area. The correlations have been used to estimate the expected number of landslides...

This method considers the parameters related to tunnel boring method and soil conditions. In this paper, design...

This demonstrates that there are inadequacies in the Hoek-Brown empirical failure criterion as currently proposed for intact rock and, by inference...

... caisson under uplift loading is included, and results of finite element modelling are presented. A simplified method for the estimation of the uplift capacity for suction caissons is described, based on the results of the finite element study. The expressions developed in this paper take into account...

... ABSTRACT: A simple method to estimate liquefaction- induced deformation was developed to estimate the settlement of river levees. In the analyses the author assumed that the residual deformation would occur in liquefied ground due to the reduction of shear modulus. Selected levees were damaged...

Therefore, statistical plans to estimate the joint distribution parameter must be discussed for a parametric estimation. We suggest serial job...
