Problems solved by technology

If there are cracks in the tunnel structure, the erosive groundwater will seep into the tunnel structure, which will lead to corrosion of the tunnel lining steel bars, structural concrete corrosion, etc., which will seriously damage the durability of the tunnel structure, thus affecting the safe performance of the tunnel.
Based on the above situation, the overhaul of the structure that affects traffic safety within the design reference period not only wastes a lot of money, but also affects the operation and use of the tunnel.

Embodiment Construction

[0016] refer to figure 1 , 2 , a disease prediction method based on tunnel environment information, including the following steps:

[0017] Step 1: Build a disease prediction model, train and predict the model based on historical data:

[0018] First, collect tunnel environmental data, including tunnel environmental information (stratum information where the tunnel is located, hydrological information, segment type, segment location, etc.), and basic tunnel information (starting and ending mileage of the tunnel, ring number, construction date, etc.).

[0019] Stratum information such as: plain fill, sand, loess, silty clay, clay, pebbles, limestone, etc.;

[0020] Hydrological information such as: rainfall, groundwater level, etc.;

[0021] Segment position such as: standard block, splicing block, etc.

[0022] Sample labeling: the diseased segment is a negative sample, and the normal segment is a positive sample. All samples are divided into training samples and predicti...

Abstract

The invention relates to a disease prediction method based on tunnel environmental information, which mainly solves the technical problem that the traditional prediction mode mostly takes a single variable as a parameter and cannot meet the actual disease prediction effect. The technical proposal of the invention comprises the following steps: step 1, building a disease prediction model and training the model based on the historical data: firstly, collecting tunnel environment data, including tunnel environment information and tunnel basic information; Sample marking: the diseased segment is negative sample, and the normal segment is positive sample; Then the machine learning algorithm is selected to iterate and optimize the model until the accuracy of the model meets the requirements. 2,classify that tunnel disease identification level: from the beginning mileage to the end mileage of the tunnel, jud whether the segments of the tunnel position are disease or not one by one, outputting the different diseases by classification through threshold setting, and finally obtaining all the diseases of each grade in the tunnel.

Description

technical field [0001] The invention relates to a tunnel environment evaluation method, in particular to a disease prediction method based on tunnel environment information. Background technique [0002] According to the incomplete statistical data on tunnel diseases, about 1 / 3 of the total tunnels have problems such as lining structure cracks and water leakage. Through investigation, it is found that a considerable proportion of tunnels have cracks and water leakage after completion and operation, and some tunnels even have lining cracks and other diseases during construction. If there are cracks in the tunnel structure, erosive groundwater will seep into the tunnel structure, which will lead to corrosion of the tunnel lining steel bars and structural concrete corrosion, which will seriously damage the durability of the tunnel structure and affect the safe performance of the tunnel. Based on the above situation, the overhaul of the structure affecting traffic safety within...
