Abstract

Groundwater overdraft in Xi'an City is the main cause of the subsidence since 1959. In recent years, ground fissure has been one of the most serious geological hazards in Xi'an, China. This paper aims to research the application of high-precision 3D terrestrial laser scanning techniques (TLS) in land subsidence and ground fissure monitoring. The paper use TLS scanning to monitor a typical ground fissure in the southern suburb of Xi'an. Large-scale subsidence is obtained by processing and comprehensive analysis these fissure data, on the other hand, the paper investigate the characteristics of spatio-temporal evolution between the land subsidence and ground fissure. Finally, compared with Global Positioning System (GPS) measurement in the same period, TLS scanning result in tested area is reliable. The research shows that there is obvious spatio-temporal correlation between land subsidence and ground fissure distribution.
