...Hua Tang; Yuwei Fang; Xu Cheng; Zhenjun Wu; Yuqiao Qin Abstract Landslides often occur along motorways in earthquake-prone areas, leading to casualties and the loss of property. Most previous studies have applied the simplified Newmark method to assess landslide susceptibility at a regional scale...

...Zhen Cui; Maochu Zhang; Qian Sheng Abstract For the seismic behavior of a rock slope or more specifically a rock wedge, the limit equilibrium method is frequently utilized to determine the static and pseudo-static safety factor, and the Newmark method is usually applied to estimate the permanent...

... the Newmark method. The inclusion of these effects was critical in determining the extent of landsliding triggered. We found that for inertially triggered slope failures modeled by the Newmark method, the ground motions used to simulate landsliding must have broadband frequency content in order to capture...

... landslide is likely to have formed aseismically even in unrealistically high ground-water conditions. Dynamic stability analysis using Newmark's method shows that both slides probably would have experienced large inertial displacements during earthquake shaking similar to that which occurred in 1811-1812...

.... Based on the test results, static slope stability analysis using Modified Bishop method and dynamic slope stability analysis using Simplified Newmark method were carried out to find out factor of safety of the slopes which is used to derive the slope stability assessment of the study area. The landslide...

... be expected from the here‐obtained results can significantly differ from those computed by the sliding‐block stability analyses based on Newmark’s method. Despite the numerous studies on the possible interaction between seismic waves, slopes, and landslides, a systematic analysis of the possible parameters...

Dynamic stability analysis using Newmark’s method shows that the landslide would have experienced large displacements – sufficient to cause catastrophic failure – during earthquake shaking similar...

... ) proposed a model to evaluate the landslide potential of a region with the input of PGA values. Newmark’s method is an efficient approach in determining the static factor of safety (FSc) needed to resist landslides using the ground acceleration due to shaking and the gradient of the slope. To estimate...

... inferred from the Newmark's model: First, by adopting Arias Intensity to quantify seismic shaking, well-established methods of seismic hazard assessment are employed to obtain the occurrence probabilities for different levels of seismic shaking in a time interval of interest. Then, some empirical relations...
