  Tensiometers and accelerometers were installed at various locations and depths (Figs. 2 and 3) within the slope to instrument the slope in order to measure the pore water pressure during the seismic loading and the post-earthquake rainfall n T5 tensiometers with an active surface area of cm 2 and a 5 mm diameter ceramic tip were Cited by: 1. this study, the soils involved in slope failure are contractive loose to medium dense sands. It has been shown that both earthquake induced inertia force and pore water pressure in sand layer play a critical role in slope stability. The loose sand layers may not always be continuous in an offshore slope. PSEUDOSTATIC SLOPE STABILITY PROCEDURE. In a pseudostatic slope stability analyss, a factor of safetyi (FS) is computed using a static limit equilibrium method in which a horizontal earthqu-akeinduced inertial force is applied to the potential sliding mass. This pseudostatic force represents the destabilizing effects of the Size: KB. This book sheds new light on improved methods for the study of the initiation and run-out of earthquake-induced landslides. It includes an initiation study method that considers tension-shear failure mechanism; an improved, rigorous, dynamic sliding-block method based on dynamic critical acceleration; and a run-out analysis of earthquake-induced landslides that takes .

Damages caused by earthquake-induced ground effects can be of the order or significantly exceed the expected damages from ground shaking. A new probabilistic technique is considered in this study for earthquake-induced landslide risk assessment. A fully probabilistic technique suggests a multi-stage hazard assessment. These stages include the determination of seismic Cited by: 1.   Earthquake-induced sliding displacement is the parameter most often used to assess the seismic stability of slopes. The expected displacement can be predicted as a function of the characteristics of the slope (yield acceleration) and the ground motion (e.g., peak ground acceleration), yet there is significant aleatory variability associated with the displacement .   So far, earthquake-induced slope instability has been evaluated by force equilibrium of soil mass in engineering practice, which cannot evaluate failure deformation once large failure occurs. An energy approach is proposed here, in which the amount of earthquake energy is evaluated in conjunction with the gravitational potential energy.

LONG-TERM EFFECTS OF EARTHQUAKE-INDUCED SLOPE FAILURES. Ikuo Towhata. The University of Tokyo Tokyo, Japan ABSTRACT The earthquake-induced slope failures are now attracting significant concerns among experts of landslides.

The reason for this is the complicated causative mechanisms as well as its impact on by: 1. earthquake occurs, the effect of earthquake induced ground shaking is often sufficient to cause failure of slopes that were marginally stable before earthquake.

According to Ranjan and Rao (), the tendency of the slope to move is construed as instability. However slope failure occurs if there is actual movement of soil mass. TheAuthor: Mohammad Anis, S.
