Abstract EN

The vertical stability analysis of the drilling shaft lining has long been a technical problem in the construction of underground space development projects.

And the critical depth of vertical stability was a key parameter to judge its stability.

To determine this parameter, a simple and practical computational method would be helpful.

In this paper, a new vertical stability analysis model of shaft lining structure based on catastrophe theory was proposed.

In accordance with the mechanical analysis, the catastrophic instability mechanics was analyzed and a new critical depth of drilling shaft lining was deduced.

Further, the rationality and feasibility of the catastrophic calculation model was proved by the numerical simulation results in a case.

And the sensitivity of the influencing parameters was also analyzed, which provided theoretic reference for optimization design and guiding security construction.

The results implied that catastrophic calculation model, as an alternative method for shaft stability analysis, could be applied to theoretical analysis and guiding engineering practice in the study of drilling shaft lining’s vertical stability.
