“…Furthermore, with the continuous advancement of construction information and automation technology, various new methods and technologies are gradually applied to the construction process, which also increases the difficulty of technical management. During the whole process of tunnel construction, the surrounding rock and support system should be monitored and measured dynamically to adjust the construction parameters in time [ 20 , 21 ], which is vital to guide the construction of the tunnel. Therefore, we make the following hypothesis: H6–Technical management positively affects tunnel construction accidents.…”

“…Generally, the deformation range of surrounding rock at the front hard surrounding rock palm is very small. e deformation of surrounding rock within the range of one time of aperture is very small and can be ignored [6]. In front of the soft surrounding rock, there is a large range of deformation.…”

With China’s fast expansion of urban traffic and railway engineering, a great number of subway and railway lines have been erected in subterranean tunnels in recent years. When the tunnel is in the process of construction, it will encounter the weak fracture zone, and the surrounding rock of this part of the tunnel is often poor stability and deformation is difficult to control, which will lead to the smooth progress of the project, delay and other problems. Therefore, to facilitate the timely treatment of tunnel soft surrounding rock, the study of image recognition of its stability is particularly important. Based on this, an improved local binary mode algorithm (ILBP) is proposed in this paper. By adjusting the weight of binary polynomial in local binary mode (LBP) operator, the target of ILBP is to extract the characteristics of weak surrounding rock of tunnel at a specific location, hoping to provide reference for the follow-up study of tunnel engineering.

“…Structure. In order to explore the dynamic response of the heavy-duty railway surrounding the rock structure of the small clearance crossing tunnel, the strain state of the soil remains small under the action of vibration load [10,11]. Special attention should be paid to the monitoring and measurement of the circumference of the tunnel with a small clear distance, a minimum clear distance, and the position of the tunnel vault, the middle of the invert, and the arch waist [12].…”

Among many tunnel construction projects, small clear tunnels have been the focus of urban rail transit construction in recent years. The purpose of this research work is to study the dynamic response characteristics of the surrounding rock structure of a heavy-duty railway with a small clearance crossing tunnel. It is proposed to analyze the dynamic response characteristics of the surrounding rock structure through the frequency response function. The vertical acceleration, tensile force, stress, and internal strength of the pipe section are specifically analyzed. The influence of the pipe joint and the assembly method on the dynamic response is also analyzed. The influencing factors of stability are analyzed from buried depth, clear distance, and surrounding rock grade. Studies have shown that the minimum clear distance of crossing tunnels increases nonlinearly with the increase of tunnel depth and gravity, and decreases nonlinearly with the increase of cohesion, internal friction angle, calculated internal friction angle, and lateral pressure coefficient. When other parameters are the same and when the side pressure coefficient is less than 1, the minimum clear distance is larger than that of the side pressure coefficient when it is equal to 1. When the vibration frequency exceeds 100 Hz, the coherence coefficient is basically close to 1, indicating that the frequency response function response result of this section is the most reliable. It is hoped that it can provide a reference for the dynamic stability analysis of the surrounding rock structure of the heavy-duty railway surrounding rock structure and the surrounding stratum and the research of structural vibration reduction technology for the small clearance crossing tunnel in the future.
