[0035] The survey anomaly data set corresponding to each mild region is constructed by the feedback type one data feature values, the feedback type two data feature values, the damage feature values, the feedback type three data feature values, the feedback type four data feature values and the state feature values.

[0036] ​​It also needs to be explained that if the feedback one type data obtained by the surveying equipment when detecting the ground is abnormal wave body data, the feedback surveying equipment of each light area during the surveying is a seismograph; if the feedback two type data obtained by the surveying equipment when detecting the ground is abnormal resistivity data, the feedback surveying equipment of each light area during the surveying is a resistivity sounding instrument; if the feedback three type data obtained by the surveying equipment when detecting the ground is abnormal spontaneous potential data, the feedback surveying equipment of each light area during the surveying is a spontaneous potential logging instrument; if the feedback four type data obtained by the surveying equipment when detecting the ground is magnetic gradient data, the feedback surveying equipment of each light area during the surveying is a proton magnetometer.

[0038] It also needs to be explained that if the feedback one type data corresponding to each light area is abnormal wave body data: compare the abnormal wave body data corresponding to each light area with the wave body data threshold stored in the database, if the abnormal wave body data corresponding to a light area is less than the wave body data threshold stored in the database, the feedback one type data characteristic value corresponding to each light area is recorded as-1, otherwise as 1, and so on, the feedback one type data characteristic value corresponding to each light area is obtained, and the feedback two type characteristic value, the feedback three type characteristic value and the feedback four type characteristic value corresponding to each light area can be obtained in the same way, and therefore are not described here.

[0039] In the specific embodiments of the present application, the determination of whether each light area exists new damage form is as follows: based on the damaged characteristic value and the state characteristic value corresponding to each light area, when , the light area numbered is recorded as not existing ground geological damage, and it is determined that the light area does not exist new damage form;

[0041] In specific embodiments of the present application, the determination of the damage area corresponding to each mild target area is specifically analyzed as follows: further investigation is performed on the mild area with new damage morphology, further underground investigation signals of the underground stage depth surface corresponding to each mild target area are obtained based on the investigation equipment, and the investigation data of the underground stage depth surface corresponding to each mild target area, i.e., the underground resistance data and the underground resistance data, are obtained.

[0042] The underground resistance data of the underground stage depth surface corresponding to each mild target area is compared with the reference underground resistance data stored in the database, and the underground resistance data of the underground stage depth surface corresponding to each mild target area is also compared with the reference underground resistance data stored in the database. If the underground resistance data of the underground stage depth surface corresponding to a certain mild target area is less than the reference underground resistance data stored in the database, or the underground resistance data of the underground stage depth surface corresponding to a certain mild target area is greater than the reference underground resistance data stored in the database, it is determined that the underground stage depth surface corresponding to the current mild target area is the damage area corresponding to the mild target area. In this way, the damage area corresponding to the mild target area is obtained.

[0043] It should be noted that if the further investigation signal feedback of the investigation equipment investigating the underground stage depth surface corresponding to each mild target area is obtained, the underground resistance data of the underground stage depth surface corresponding to each mild target area is the shear strength, and the underground resistance data is the resistance value, then the feedback investigation equipment of the underground stage depth surface corresponding to each mild target area is the static sounding instrument.

[0044] It should be noted that the reference underground resistance data and the reference underground resistance data are set by professional investigation personnel; the reference underground resistance data and the reference underground resistance data are reference values for determining whether the mild target area has a damage area.

The functional types of the damaged locations in each severely affected area are compared with the set of functional types of various functional survey equipment used under geological disasters stored in the database. If the functional type of a damaged location in a severely affected area is within the set of functional types of a certain functional survey equipment used under geological disasters stored in the database, then that functional survey equipment is taken as the application survey equipment corresponding to that severely affected area. This comparison is repeated to obtain the application survey equipment corresponding to each severely affected area.

[0048] In a specific embodiment of the present invention, the analysis of whether tail-related damage will form between each severely damaged area and its adjacent areas is carried out as follows: Based on the application of surveying equipment, surveys are conducted between each severely damaged area and its adjacent areas. According to the surveying equipment in data feedback mode during the survey, corresponding detection data between each severely damaged area and its adjacent areas are obtained, including continuous low-reflection data, seismic wave data, and distortion data. This detection data is imported into the regional tail-related damage assessment model, and then the damage cascading result value between each severely damaged area and its adjacent areas is analyzed. If the damage cascading result value between a severely damaged area and its adjacent area is 1, it is determined that tail-related damage has formed between the severely damaged area and its adjacent area, and further surveys are conducted under the condition of tail-related damage between the severely damaged area and its adjacent area. If the damage cascading result value between a severely damaged area and its adjacent area is 0, it is determined that tail-related damage has not formed between the severely damaged area and its adjacent area. This process is used to analyze whether tail-related damage has formed between each severely damaged area and its adjacent areas.

For the first corresponding distortion data between each severe area and the adjacent area, a reference area tail series damage value set.

[0050] It should be noted that if the continuous low reflection data between each severe area and the adjacent area is continuous low reflection frequency by using the surveying equipment, the surveying equipment in data feedback during the surveying between each severe area and the adjacent area is the geological radar; if the seismic wave data between each severe area and the adjacent area is seismic wave velocity by using the surveying equipment, the surveying equipment in data feedback during the surveying between each severe area and the adjacent area is the acoustic logging instrument; if the distortion data between each severe area and the adjacent area is waveform distortion rate by using the surveying equipment, the surveying equipment in data feedback during the surveying between each severe area and the adjacent area is the oscilloscope surveying.
