“…From the point of view of the location of the disease, different diseases occurred in the upper arch wall structure and the lower tunnel bottom structure of the heavy-duty railway tunnel [22]. Comparing the disease rates of passenger-cargo railway tunnels and heavy-duty railway tunnels, the disease rate of heavy-duty railway tunnels is much higher than the average disease rate of the whole road tunnel, indicating that the high disease rate of heavy-duty railway tunnels is its primary feature [23].…”

At present, the world-wide heavy-haul transportation technology of cargo trains has developed rapidly. Heavy-haul railway transportation has received extensive attention due to its large capacity, high efficiency, and low transportation costs. In order to understand the role that ferroelectric materials can play in the dynamic response of a heavy-duty railway surrounding rock structures in crosstunnels, this article introduces the domain structure of ferroelectric materials, derives the calculation method of the dynamic response of the surrounding rock structure, simulates the dynamic response characteristics through the corresponding formula, and analyzes the changes of the heavy-duty railway in the presence and absence of water. The situation was analyzed. The research results found that the increase of axle load will increase the bending moment of the invert structure. When the axle load is 30 t, the V-class surrounding rock is the most unfavorable working condition and the bending moment value of the invert structure is the largest at this time. When the added value of contact pressure is generally around 6.5 kPa, the railway as a whole can maintain a stable state.

“…5 Therefore, tunnels in squeezing rock are one of the urgent problems to be solved at home and abroad. [6][7][8] We know that there is no uniform international standard for large deformation, and we can get a preliminary understanding of the large deformation through the cognition of the relevant researchers. For example, Yu 9 thought that the large deformation means that the displacement of single-track tunnel exceeds 25 cm and that of double-track tunnel is 50 cm.…”

Field studies by squeezing rock deformation have shown that large deformation slips can occurs in tunnels in squeezing rock, the tunnels may be partially or completely broken. This article proposed two schemes for controlling the deformation of squeezing rock, which are “resistance combine release” Scheme 1 and “strong support” Scheme 2, the deformation characteristics and deformation mechanism of squeezing rock is researched by Zhongyi Tunnel. The results show that Scheme 2 is superior to Scheme 1 in terms of deformation rate, cumulative deformation, and monthly construction footage. Research results can provide a reference for similar projects.
