“…Scene changes will develop to a certain extent and become qualitative changes, which are indifferentiable. Functions, such as earthquakes, volcanic eruptions, tsunamis, stratum movement, etc., for these common discontinuities in the material world, the use of catastrophe theory can better explain the nature of these phenomena [13][14][15]. With the in-depth understanding of the material world, people began to realize the need for a non-linear, discontinuous theory to study these material phenomena.…”

With the continuous development of society and economy, infrastructure construction is expanding on a large scale. The stress concentration after excavation in deep-buried soft rock masses may cause the stress level of the rock mass to exceed the strength of the surrounding rock and form plastic stress, the area where plastic shear slip or plastic flow occurs. Based on the fuzzy logic matching algorithm for the surrounding rock of deep-buried soft rock tunnel construction, this paper analyzes the development law of surrounding rock deformation and supporting force over time in actual construction by establishing elementary function mathematical calculation equations, and tries to construct a set of It is used to determine the actual deep-buried soft rock tunnel surrounding rock stability limit displacement value process. Practical results show that the process based on fuzzy logic matching algorithm can effectively meet the requirements of actual deep-buried soft rock tunnel engineering.
