Description

technical field [0001] The invention relates to the field of tunnel disease detection, in particular to a tunnel leakage rate prediction method based on a convolutional neural network and a long-short-term memory network. Background technique [0002] Due to changes in natural conditions (groundwater, materials, strata, freeze-thaw, etc.), various variations (such as cracks, dislocations, etc.) occur in the tunnel structure, resulting in direct or indirect groundwater or surface water in the surrounding rocks in the form of leakage or gushing. Forms enter the tunnel, forming tunnel leakage disease, eroding the tunnel structure, and affecting the normal operation of the tunnel and the use of equipment in the cave. [0003] At present, the investigation of leakage diseases in tunnels mainly adopts the methods of manual patrolling, photographing and on-site recording, focusing on the area of ​​seepage and the rate of leakage. The workload is heavy, the efficiency is low, and it...

[0006] The above-mentioned patents all use machine learning methods to detect and study tunnel water leakage diseases. Although the automatic identification of water leakage diseases is realized, the rate of water leakage is not predicted and analyzed, and the risk prediction of tunnel structural safety cannot be carried out.
