Slope failure cause evaluation based on earthworks management and meteorological conditions analyses
Slope failure cause evaluation based on earthworks management and meteorological conditions analyses
Rainfall-triggered slope failures are a well-known cause of disasters. To increase the stability of slopes a retaining wall is often proposed. However, associated earthworks could bring the great danger of a landslide during the construction process, if not properly managed. The paper aims to investigate the collapse cause of residential buildings located at the edge of the slope in the northwest part of Vietnam, where engineering works were performed to prevent failure due to undercutting soil erosion. During the retaining wall construction works, significant vibrations and additional dynamic loads could have affected the building foundations' bearing capacity, leading to structural failure. Another cause is associated with heavy precipitation recorded at the site just after the excavation works down the slope. The paper consists of analyses allowing simulation of possible scenarios, including the effect of changing saturation conditions using the metrological data. The analyses concerned slope stability improvement to secure the remaining infrastructure.
