Experimental Study on Bedding Landslide Disaster Based on Temperature and Strain Response |
| |
| Abstract: | Through indoor model test, the data of strain, temperature and bending moment in the slope body and sliding zone under rainfall condition are obtained by using fiber Bragg grating temperature and strain sensors and strain gauges. The evolution mechanism of bedding landslide under rainfall condition is studied, The study finds that the deformation characteristics of slope body are traction → displacement → traction, and the slope temperature is related to rainfall and slope deformation. |
