Tunnel mid-partition wall wind pressure monitoring and danger early warning method

The invention belongs to the technical field of wind pressure monitoring, and provides a tunnel mid-partition wall wind pressure monitoring and danger early warning method for solving the problems that an existing tunnel mid-partition wall wind pressure monitoring method is large in error and cannot reflect the real stress condition of a mid-partition wall. The method comprises the steps: step 1,selecting a wind pressure monitoring section; step 2, mounting and arranging a wind pressure monitoring system; step 3, setting control parameters of a signal acquisition instrument and a sensor base,and setting a monitoring period; step 4, acquiring and uploading wind pressure data; step 5, carrying out equation fitting and superposition of the data; step 6, calculating the overall stress; and step 7, carrying out stability checking calculation and danger early warning of the mid-partition wall. According to the invention, the problem of high-frequency, high-precision and multi-directional wind pressure monitoring in
