Abstract In order to provide a more comprehensive and effective new method for real-time monitoring of slope deformation，a set of technical methods for real-time monitoring of reservoir bank slope deformation using Micro Electro-Mechanical System(MEMS) inertial sensors is proposed. On the basis of the traditional displacement measurement，the rotation angle measurement is added in the proposed methods，which can more comprehensively observe the three-dimensional motion state of the slope deformation. To observe the slow static deformation of slope body at the initial stage of bank slope deformation，a three-dimensional electronic compass composed of a micro-accelerometer and a micro-magnetometer is used to measure the gravitational acceleration and magnetic field strength of the observation point in the three-dimensional direction of the installation position of the sensor. Using the principle of inertial measurement，the measured axial gravitational acceleration components and magnetic field strength components are converted into the horizontal and vertical rotation angles of the observation point. Furthermore，referring to the global navigation satellite system(GNSS) measurement data，the rotation angle and translational displacement of the observation point can be obtained at the same time. To observe the dynamic deformation of the slope body from the accelerated deformation of the bank slope to the failure stage，the linear acceleration and angular velocity of the observation point are measured by the inertial measurement unit composed of micro-accelerometer and micro-gyroscope. According to the principle of inertial navigation，the measured linear acceleration and angular velocity are converted into the motion velocity and displacement of the observation point. So that，the rapid early warning of the bank slope landslides is achieved. In this paper，an application example of the static deformation monitoring of the reservoir bank slope in the initial stage of deformation is given. Furthermore，the inertial sensor measurement of the dynamic deformation of the bank slope from the acceleration deformation to the failure stage is simulated and analyzed. The example monitoring and simulation results show that it is feasible to use the inertial sensor measurement technology to monitor the static and dynamic deformation of the reservoir landslide in real time，which is helpful to fully understand the real-time state of the slope deformation.

Key words： slope engineering MEMS inertial sensor reservoir landslide static deformation dynamic deformation real-time monitoring emulation and simulation
