Application of GPS-RTK Technology in the Measurement of Discontinuity Traces

Abstract:

Rock discontinuities appear as traces on exposures such as natural outcrops or tunnel walls. Discontinuity size which has important effects on rock mass behavior such as rock mass strength, deformability, stability, fluid flow, contaminant transport is related to trace length. Field linear and areal sampling techniques are time-consuming and low accuracy. Real-Time Kinematic GPS (GPS-RTK) developed from GPS is a more secure and fast way, which has some advantages of shorter observation time, high positioning accuracy, unnecessary intervisible and direct result of exact coordinate in field. This paper uses GPS-RTK technology in the measurement of discontinuity traces in Beishan granite rock mass of Gansu province. Through analyzing the processing and results acquired from Beishan granite rock mass discontinuity traces, the paper tries to demonstrate the feasibility and practicality of the method.
