Tunnel management and maintenance engineering scheme completeness evaluation method based on fault tree analysis method

The invention relates to a tunnel management and maintenance engineering scheme completeness evaluation method based on a fault tree analysis method, and the method comprises the steps: employing a brand new design logic, building a fault tree based on an incomplete evaluation as a top event corresponding to a preset tunnel type engineering scheme, and a preset key factor event of each management and maintenance project related to the tunnel type engineering scheme; the method comprises the following steps: firstly, determining a weight corresponding to each basic event in a fault tree, and then obtaining a sensitive factor corresponding to each management and maintenance project key factor event; and finally, comparing the target tunnel management and maintenance scheme with each missing end basic event corresponding to the fault tree to obtain an incomplete evaluation corresponding to the target tunnel management and maintenance scheme. The design and construction of the fault tree fully considers each link
