Abstract: In order to analyze the characteristics of deformation field in central Yunnan water diversion project area, based on multistage GNSS observation data, cross-fault monitoring data, and by means of velocity field clustering, least squares collocation algorithm and with fault rigid-body motion model, current movement rates and strain rates of main active faults in this area were deduced, the processes of three dimensional movement of active faults were also resolved.The results indicated that the southern segment of Xiaojinhe-Lijiang fault and Xiaojiang fault had always been two strong deformation zones, the recent regional tectonic movement of Chuxiong segment of the water diversion route was relatively stable.The eastern margin fault of Jianshui basin was characterized as high level of shear stress accumulation.The active mode of southern segment of Lijiang-Jianchuan fault had converted from tensile strike-slip to compressive strike-slip since 2011.After 2018,the southern segment of Lijiang-Jianchuan fault had a lower strike-slip rate, while the extension of southeast segment of Qujiang fault was strong.The research results can provide reference for stability analysis of cross-fault long line project sites and faults movement resistance design of engineering structures.
