Abstract
Description
Technical Field
[0001] This invention relates to the field of data processing technology, and in particular to an artificial intelligence-based system for identifying and analyzing the risks of tunnel entrance slopes. Background Technology
[0002] During tunnel construction, the tunnel entrance inevitably experiences the removal of soil and rock at the slope toe due to the excavation of the side slopes and tunnel body, creating an unfavorable open face. This disrupts the original equilibrium of the slope, causing instability of the entrance and exit slopes, which can lead to the tunnel entrance being covered and compressed. This poses a serious threat to the safety of tunnel construction and operation. Therefore, identifying and analyzing the risks of tunnel entrance slopes can improve the stability of tunnel construction to a certain extent.
[0003] A search revealed that existing tunnel portal risk identification methods all involve dividing the tunnel portal into regions, monitoring and analyzing the resulting regions, and then performing multiple divisions based on the monitoring results to determine the final risk area. However, this process of multiple region divisions and monitoring of the tunnel portal results in some resource waste, and the risk area may be segmented during these multiple divisions, thus affecting the accuracy of risk identification. Therefore, how to avoid the resource waste and inaccuracy caused by region division in tunnel portal risk identification is a problem we need to solve. To this end, this invention proposes an artificial intelligence-based tunnel portal slope risk identification and analysis system. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely too heavily on a single slope parameter, resulting in insufficient accuracy in risk identification.
