Abstract: An assessment method for seismic landslide hazard based on a LS-D-Newmark model is performed as follows. Historical landslide data is acquired, and a historical landslide density is determined. The historical landslide data is input into the LS-D-Newmark model, and model parameters are adjusted, such that a static safety factor Fs of a slope is greater than 1 in the absence of external forces. The historical landslide density is introduced to the LS-D-Newmark model, and assignment of the static safety factor Fs is optimized to obtain an optimized static safety factor Fs-L. A slope critical acceleration ac-L and an earthquake-induced slope displacement Dn-L, are calculated to calculate a landslide occurrence probability P of a target landslide region. An assessment device, a processing device, and a computer-readable storage medium for implementing the method are further provided.

Abstract: Disclosed is a tunnel protection structure suitable for active fault areas and high ground stress areas, and relates to the technical field of tunnel engineering construction. The tunnel protection structure comprises at least one protection unit, wherein a plurality of protection units are sequentially connected and distributed along the axial direction of a tunnel, and the protection units comprise a radial protection ring and two axial protection rings which are fixedly arranged between a lining structure and surrounding rock and are distributed along the axial direction of the tunnel; the radial protection ring comprises a plurality of radial buffer energy consumption layers which are sequentially sleeved along the radial direction of the tunnel; and the axial protection ring comprises a plurality of axial buffer energy consumption layers which are sequentially and fixedly connected along the axial direction of the tunnel.
