A rockfall in Guizhou<\/h5>\n

One News in New Zealand has an interesting news report<\/a> including a video of a rockfall event along a highway in Guiyang in Guizhou Province.\u00a0 The video is embedded from Youtube below<\/a>, which includes a nice set of images of the aftermath and replays the collapse event several times.<\/p>\n

Fortunately the potential for collapse had been identified and the road had been closed.\u00a0 The collapse event appears to have happened on a pre-existing basal release surface and to be defined by a set of existing vertical joints – i.e. in essence this is a complex wedge failure, as this screenshot shows:<\/p>\n

This collapse is the result of a failure to properly assess the discontinuities in the rock mass during construction.\u00a0 Such events should be avoidable with proper engineering geological assessment and mitigation.<\/p>\n

Meanwhile, Getty Images has a gallery<\/a> showing landslides triggered by the 5th August 2014 earthquake in Yunnan Province.\u00a0 I cannot include them here, they are worth a look if you get a chance. Earlier this week six members of a team trying to drain one of the valley-blocking landslides were killed when the dam rapidly failed<\/a>.\u00a0 A further 2000 people had to be evacuated.<\/p>\n","protected":false},"excerpt":{"rendered":"
