Sdudy on Stability and Prevention and Cure Project of Dangjiaba Landslide in Xunyang

摘要

Dangjiaba landslide in Xunyang under natural condition is stable, whose surface locally exists shallow slipping signs. Currently, the slope toe is excavated because of real estate development. So, many tensile cracks are produced from these artificial engineering actions. Cracks existing at both sides of slope surface tend to cut-through, which illustrates the critical situation of the landslide. Then, the emergency measure such as weighting at toe of slope and sealing these cracks is taken. And the surveying, stable estimation and prevention-cure design are done. This landslide is typically triggered by human being, whose slip mode is pull-type. There exist the important power and communication facilities on the slope, so the anti-slip pile is considered. Aiming to be taken warning by hither engineering in this area.
