The Research on Secondary Slope Stability of Mountain Substation
摘要
Abstract
Fellenius method is an effective means of mountain substation slope stability analysis ,combining with the actual monitoring optical fiber sensing technology to further verify the stability of the slope. Use Fellenius meth⁃od to check the slope stability,analyzing the factor of safety. Layout surface cracks type sensors monitor the slope surface should be variable,the actual monitoring results show that the strain change on the surface of the sensor IS3 is nearly 540με,the strain change under the surface of sensor IS4 is nearly 120με,the strain change of sensor IS5 is nearly 120με. Distributed surface laid fiber sleeve,and the use of surface deformation monitoring slope OTDR method,the actual monitoring results show that the attenuation coefficient of optical fiber link is 12.567 dB/km,the attenuation curve has good linearity,no significant steps determines the slope in a stable state.关键词
