Earthquake Induced Permanent Displacement of Slopes: a Numerical Study (TECHNICAL NOTE)
The conventional method to evaluate earthquake induced permanent deformations of slopes is the one proposed by Newmark. In this paper, permanent displacement of slopes is studied using a combination of distinct element and finite difference methods and the results of these numerical evaluations are compared with those of the Newmark's approach. Several parameters involved, including peak ground...
متن کاملA Monte Carlo simulation technique for assessment of earthquake-induced displacement of slopes
The dynamic response of slopes against earthquake is commonly characterized by the earthquake-induced displacement of slope (EIDS). The EIDS value is a function of several variables such as the material properties, slope geometry, and earthquake acceleration. This work is aimed at the prediction of EIDS using the Monte Carlo simulation method (MCSM). Hence, the parameters height, unit specific ...
متن کاملOptimized volume models of earthquake-triggered landslides
In this study, we proposed three optimized models for calculating the total volume of landslides triggered by the 2008 Wenchuan, China Mw 7.9 earthquake. First, we calculated the volume of each deposit of 1,415 landslides triggered by the quake based on pre- and post-quake DEMs in 20 m resolution. The samples were used to fit the conventional landslide "volume-area" power law relationship and t...
متن کاملEarthquake Ruptures on Rough Faults
Natural fault surfaces exhibit roughness at all scales, with root-mean-square height fluctuations of order 10−3 to 10−2 times the profile length. We study earthquake rupture propagation on such faults, using strongly rate-weakening fault friction and offfault plasticity. Inelastic deformation bounds stresses to reasonable values and prevents fault opening. Stress perturbations induced by slip o...
متن کاملDetermination of Coseismic Displacement Field in Saravan Earthquake in 2013 on Iranian Permanent GPS Network for Geodynamics (IPGN)
The Makran subduction zone from the point of view of Tectonics, and seismicity is really interesting for researchers. The Makran zone is divided into two parts of western Iran and east in Pakistan. The largest earthquake of the last half century, with magnitude 7.8 in 2013, occurred near the city of Saravan. The occurrence of this earthquake indicates the locks on the western Makran border wit...
