Soil Slopes

The permanent displacement has been widely used for slope seismic stability in practical engineering; however, the effect of the dynamic pore water pressure on the saturated and unsaturated soil slopes could not be neglected. In this paper, we propose a calculation method of dynamic pore water pressure by the hollow cylinder apparatus (GCTS) which is the most advanced and complicated device in lab testing on soil dynamics. Then, based on the proposed calculation method of dynamic pore water pressure combined with the limit equilibrium and finite element methods, we introduce a simple calculation method of permanent displacement, which avoids solving complex nonlinear equations and greatly simplifies the computational effort. Shaking table test results demonstrate the effectiveness and efficiency of the simple calculation method of permanent displacement, which could rapidly assess the soil slope seismic stability considering the effect of dynamic pore water pressure.

Rupture Mechanism

Near fault ground motions can be significantly different than those further away from the seismic source. Within the near fault zone ground motions are drastically influenced by the rupture mechanism, the direction of rupture propagation relative to the site and possible permanent displacement related to the fault slip. During the past two decades several sophisticated theoretical or/and empirical methods have been proposed to simulate near fault motion requiring input parameters that hardly can be provided with accuracy, leading thus to extended parametric studies and uncertainties. In this paper, a simple but effective analytical model that mathematically represents near fault ground motions (Mavroeidis and Papageorgiou, 2003) is applied and tested in the case of Cephalonia, Feb. 3, 2014 earthquake (Μ6.0). Its validity and reliability are examined and an effort to distinguish source and possible site effects is attempted for the town of Lixouri (LXR1 accelerograph) where the highest damage levels was observed.
