Abstract
Provided is a perception evaluation method for a bearing capacity of a highway tunnel lining structure, including: from the load effect evolution state of surrounding rock and the decay mechanical state of a lining structure, the characterization index system of a highway tunnel bearing capacity is constructed; a characterization index inversion function relationship based on strain data of an inner surface of the highway tunnel lining is provided, a bearing capacity perception layout scheme of the tunnel structure is constructed accordingly, and a complete set of perception method for bearing capacity characterization indexes is obtained; then, by calculating a load effect function and a resistance effect function, the calculation and evaluation method of the tunnel structure bearing capacity.
