Corrugated steel plate lining reinforcement parameter optimization design method and structure based on tunnel lining defect detection

Abstract

The invention discloses a corrugated steel plate lining reinforcement parameter design method and structure based on tunnel lining defect detection. The corrugated steel plate lining reinforcement parameter design method is composed of five parts including corrugated steel plate geometric parameter design, corrugated steel plate geometric partitioning design, corrugated steel plate connecting component design, corrugated steel plate durability design and corrugated steel plate safety checking calculation, wherein the design is ended only when all safety checking calculations are passed, and otherwise, the design process needs to be executed again. The corrugated steel plate lining reinforcement parameter design method based on tunnel lining defect detection can provide a reasonable and effective method for selection and quantitative design of a tunnel corrugated steel plate lining reinforcing structure, and avoids blindness and randomness of a traditional design method, and the whole design process is clear in quantification, convenient to implement, safe, reliable, economical, applicable, scientific and reasonable and the corrugated steel plate lining reinforcement parameter design method has wide popularization prospects.

AI Technical Summary

Problems solved by technology

This method has three shortcomings. The first is that the rationality of the corrugated steel lining reinforcement parameters largely depends on the engineer's work experience in similar tunnel strata, hydrogeology, surrounding rock grades, buried depths, and lining disease degrees. The accuracy of the relevant parameters cannot be fully guaranteed; the second disadvantage is that the damage of the corrugated steel plate arch structure as a steel structure is often due to the buckling-induced instability failure rather than the ultimate failure of the bearing capacity, so the calculation value is only based on the force deformation The feedback adjustment is obviously not comprehensive, and the stability analysis of the corrugated steel plate lining should be supplemented; the third disadvantage is that the overall load-carrying conditions of the damaged secondary lining, filling layer and corrugated steel plate are not considered, resulting in a larger calculation value of the corrugated steel plate stress and deformation. It may lead to further strengthening of corrugated steel plate specifications, resulting in design waste
