Abstract


Slope stability has a crucial role in the safe operation of the engineering , slope stability analysis is particularly critical . Is the master slope deformation in real time , the effect of the test design and construction , and research needs in situ monitoring of the slope is an important means . In this paper, relying on engineering K47 900, K54 940 and K56 385 three slope site deep displacement , the anchor stress , concrete strain monitoring , and the use of state-of-the-art fiber grating sensing monitoring technology . According to the monitoring data , take to the slope deformation and stress releasing regularity unsteady deformation of heavy rainfall on the slope and draw conclusions , and verify the feasibility and advantages of fiber grating sensing technology . Stability analysis method traditional limit equilibrium method and the rapid development in recent years , finite element strength reduction . The finite element method considering the geotechnical material of constitutive relations , and the ability to automatically search for the sliding surface is generated , the calculated results are relatively accurate , and therefore become more popular . In this paper, the finite element method based on the project at K47 900 slope excavation process simulation , and the use of strength reduction analysis of slope stability , draw the reasonable step of slope excavation and slope stability conclusions.
