- Abstract
On June 5, 2009, a catastrophic landslide occurred in Wulong, Chongqing, China. Landslide seismology analysis and numerical modeling were used in this work to reproduce the runout behavior of the Jiweishan landslide for further thermal investigation. We adopted a two-dimensional frictional heating model to improve the accuracy and comprehension of thermal effects during landslide occurrences. Based on landslide process reconstruction, the frictional heating mechanism was revealed in the shear zone. A quasi-two-dimensional thermal analysis was performed to investigate temporal evolution and spatial distribution of friction-induced temperature within the shear zone. The simulation concludes with a maximum temperature of 920 °C, while the shear zone temperatures under the front and rear blocks are 425 and 68 °C, respectively. The frictional heating model is then used to investigate the thermal response along the sliding direction. Furthermore, the other potential thermal effects were discussed according to the temperature distribution. The work conducted in this study is expected to provide valuable information for dynamic behavior prediction and further investigation of the thermal effects of long-runout landslides.
