With increase of population and exploitation of land resources, slope problem has become one of three global geological disasters, ranking with earthquake and volcano. Owing to slope instability, collapse, landslide and debris flow brought massive loss for people’s life and property, slope stability problem becomes more and more prominent. It involves excavation slope of high-rise […]

Before rupture surface appearing in rock slope, its change characteristics belong to deformation characteristics and after penetrating rupture surface appearing, it belongs to failure characteristic. Its development processes are: loose or tension crack, rock mass creep, accelerated creep and failure. The first three steps are deformation characteristics and the last step is failure characteristic. 1. […]

SDA bolt is a kind of supporting technology in geotechnical engineering. It drills surrounding rocks with a certain distance, direction and depth, then it is put into the drill hole and at last, grouting and fixing are carried on. SDA bolt has the effect of binding, combining and reinforcing surrounding rocks. It helps to improve […]
