On the use of different data assimilation schemes in a fully coupled hydro-mechanical slope stability analysis

Mohsan, Muhammad; Vossepoel, Femke C.; Vardon, Philip J.

2023 Georisk Assessment and Management of Risk for Engineered Systems and Geohazards

doi:10.1080/17499518.2023.2258607

Different data assimilation schemes such as the ensemble Kalman filter (EnKF), ensemble smoother (ES) and ensemble smoother with multiple data assimilation (ESMDA) are implemented in a hydro-mechanical slope stability analysis. For a synthetic case, these schemes assimilate displacements at the...

Analysis on the volume expansion effect and influencing factors on loess landslides: a case study of the Heifangtai tableland in the Chinese Loess Plateau

Kong, Jia-xu; Zhuang, Jian-qi; Peng, Jian-bing; Ma, Peng-hui; Zhan, Jie-wei; Mu, Jia-qi; Wang, Jie; Wang, Zuo-peng

2023 Georisk Assessment and Management of Risk for Engineered Systems and Geohazards

doi:10.1080/17499518.2023.2257201

Landslide scale measurement and hazard risk assessment are crucial, especially since landslide deposits often have an expansion effect, and can lead to more serious secondary hazard events. In this study, we obtained substantial high-resolution terrain and orthophoto data through multiple UAV...

PDEM-based seismic performance evaluation of circular tunnels under stochastic earthquake excitation

Huang, Zhong-Kai; Ning, Chao-Lie; Zhang, Dong-Mei; Huang, Hong-Wei; Zhang, Dong-Ming; Argyroudis, Sotirios

2023 Georisk Assessment and Management of Risk for Engineered Systems and Geohazards

doi:10.1080/17499518.2023.2257171

Tunnels are a vital component of urban infrastructure that must be robust against seismic hazards. Given the randomness of earthquake occurrence, the seismic response of tunnel structures mut be studied by stochastic analysis methods. To this end, this study proposes a probability density...
