Description

Technical Field

[0001] The present application relates to the technical field of civil geological engineering safety assessment, and in particular to a method and system for evaluating the stability of a fill slope. Background Art

[0002] Fill slope stability evaluation is a key link in civil engineering and geological engineering. It aims to evaluate the stability of fill slopes under different conditions and ensure their safety during long-term service. Generally speaking, the slope displacement deformation data, settlement deformation data and the number of cracks in the slope can be collected through the slope monitoring system. The stability trend of the slope can be analyzed based on the above parameters. When any data is abnormal, the slope monitoring system will issue a warning to the background. At this time, it is necessary to dispatch staff to conduct on-site surveys to ensure the stability of the slope. However, when the slope is deformed, it is possible that none of the above three parameters reach abnormal levels. In order to ensure the stability of the slope, it is necessary to conduct a stability evaluation of the slope based on the parameters collected by the slope monitoring system.

[0059] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0061] The present application provides a method for evaluating the stability of a fill slope, which can analyze and evaluate the stability of a fill slope to determine the state of the fill slope and take corresponding reinforcement measures and plans.

[0062] In the first aspect, the present application provides a method for evaluating the stability of a fill slope. Figure 1 ,The specific steps included in a method for evaluating the stability of a fill slope are as follows.

[0063] Step S110: Obtain historical monitoring data of the slope to be evaluated by the slope monitoring system and monitoring and collection data of the slope to be evaluated by the slope monitoring system within a preset time period; the historical monitoring data includes historical displacement data, historical settlement data, historical crack data and historical warning data; the preset time period is the time period from the last warning to the current time; the monitoring and collection data includes slope displacement data, slope settlement data and slope crack data.

[0064] In the embodiment of the present application, the stability of the slope is specifically analyzed based on the three types of data of slope displacement, settlement and cracks collected by the slope monitoring system; it can be understood that the relevant data collected by the slope monitoring system are stored in the cloud server; specifically, the slope monitoring system, such as the HC-GBSAR synthetic aperture radar slope monitoring system, can realize the collection of the above-mentioned slope displacement, settlement, cracks and other data.

[0065] It is understandable that when any of the displacement data, settlement data and crack data of the slope reaches the preset warning threshold, the system will issue a warning to the background to indicate that the slope has deformed and that staff need to be dispatched for field surveys; in this application, the preset time period is a comprehensive analysis of the current stability of the slope based on the three deformation data.

[0066] Step S120: calculating basic slope stability data based on the monitoring and collected data; the basic slope stability data is negatively correlated with the slope displacement data, slope settlement data, and slope crack data.

[0067] In an embodiment of the present application, calculating the basic slope stability data based on the monitoring and collected data specifically includes calculating displacement deviation data based on the slope displacement data of the first day and the slope displacement data of the last day within the preset time period; calculating settlement deviation data based on the slope settlement data of the first day and the slope settlement data of the last day within the preset time period; calculating crack deviation data based on the slope crack data of the first day and the slope crack data of the last day within the preset time period; and calculating the basic slope stability data based on a preset slope original stability value, the displacement deviation data, the settlement deviation data, and the crack deviation data.

[0068] The calculation method of basic slope stability data specifically includes:

[0069] Assuming that the preset time period is n days, the slope displacement data of the i-th day is , then the slope settlement data on day i is , then the slope crack data on day i is ;

[0070] ;

[0071] ;

[0072] Where, is the basic data of slope stability, is the preset original stability value of the slope; is the intermediate value calculated instead; is the displacement deviation data, is the settlement deviation data, is the crack deviation data; are respectively a preset first weight, a preset second weight and a preset third weight; and, .

[0073] It is understandable that the crack data here can adopt the data of changes in the number of cracks; for example, there is 1 crack on the first day and 4 cracks on the last day; it is understandable that for a slope, its deformation time may be very long or very short, depending on the specific situation.

[0074] It should be noted that the preset original slope stability value here is the default initial value, a conventional parameter, and a fixed value for the convenience of calculation; the V here is used as an intermediate parameter for calculation and has no practical significance.

[0075] Step S130: analyzing slope stability impact data based on the historical monitoring data and the monitoring collection data; the slope stability impact data is associated with the historical displacement data, historical settlement data, historical crack data, and historical warning data.

[0076] In an embodiment of the present application, analyzing the slope stability influencing data according to the historical monitoring data and the monitoring and acquisition data specifically includes: determining a historical displacement time period, a historical settlement time period, and a historical crack time period according to the historical monitoring data and the monitoring and acquisition data; the historical displacement time period is a time period in which the displacement deviation data of any time period in the historical monitoring data is the same as the displacement deviation data of the preset time period; the historical settlement time period is a time period in which the settlement deviation data of any time period in the historical monitoring data is the same as the settlement deviation data of the preset time period; the historical crack time period is a time period in which the crack deviation data of any time period in the historical monitoring data is the same as the crack deviation data within the preset time period; calculating the historical settlement deviation data and the historical crack deviation data of the historical displacement time period; calculating the historical settlement deviation data and the historical crack deviation data of the historical settlement time period. The method comprises the following steps: calculating the historical displacement deviation data and the historical crack deviation data of the historical crack time period; calculating the settlement deviation data of the historical crack time period; calculating the settlement crack influence data according to the historical settlement deviation data and the historical crack deviation data of the historical displacement time period and the settlement deviation data and the crack deviation data of the preset time period; calculating the displacement crack influence data according to the historical displacement deviation data and the historical crack deviation data of the historical settlement time period and the displacement deviation data and the crack deviation data of the preset time period; calculating the displacement-settlement influence data according to the historical displacement deviation data and the historical settlement deviation data of the historical crack time period and the displacement deviation data and the settlement deviation data of the preset time period; and analyzing and calculating the slope stability influence data according to the settlement crack influence data, the displacement crack influence data and the displacement-settlement influence data.

[0077] The calculation method of slope stability impact data specifically includes:

[0078] Assuming there are n historical displacement time periods, the historical settlement deviation data of the i-th historical displacement time period is: , the historical crack deviation data of the i-th historical displacement time period is ; Calculate the displacement duration deviation data based on the duration of the historical displacement time period and the duration of the preset time period; then the displacement duration deviation data corresponding to the i-th historical displacement time period is ;

[0079] Assuming there are m historical settlement time periods, the historical displacement deviation data of the jth historical settlement time period is: , the historical crack deviation data of the jth historical settlement period is ; Calculate the settlement duration deviation data based on the duration of the historical settlement time period and the duration of the preset time period; then the settlement duration deviation data corresponding to the j-th historical settlement time period is ;

[0080] Assuming there are q historical crack time periods, the historical displacement deviation data of the pth historical crack time period is: , the historical settlement deviation data of the pth historical crack time period is ; Calculate the crack duration deviation data based on the duration of the historical crack time period and the duration of the preset time period; then the crack duration deviation data corresponding to the pth historical crack time period is ;

[0081] ;

[0082] Where, is the slope stability impact data, is the displacement deviation data, is the settlement deviation data, is the crack deviation data; The data on the impact of settlement cracks are: is the displacement crack impact data, The displacement and settlement impact data; are respectively a preset fourth weight, a preset fifth weight and a preset sixth weight; and, .

[0083] It can be understood that for the displacement deviation data, settlement deviation data and crack deviation data of the preset time period, in the historical monitoring data, there must be any time period of indeterminate length of displacement deviation data, settlement deviation data and crack deviation data that are the same as any of the three data of the above-mentioned preset time period; therefore, by controlling one of the variables to be the same, analyzing the similarity of the other two data, and then combining the similarity of the time length, the impact of similar time periods on the preset time period in the historical monitoring data can be calculated.

[0084] The calculation method for the displacement duration deviation data here is to divide the duration of the historical displacement time period by the duration of the preset time period; the settlement duration deviation data and crack duration deviation data can be obtained similarly.

[0085] Step S140: determining slope stability comprehensive evaluation data according to the slope stability basic data and the slope stability influencing data, and determining a slope survey suggestion based on the slope stability comprehensive evaluation data.

[0086] It can be understood that the comprehensive evaluation data of slope stability = basic slope stability data * slope stability influencing data; after obtaining the comprehensive evaluation data of slope stability, the comprehensive evaluation data of slope stability is compared with the preset data comparison table, which contains the correspondence between the comprehensive evaluation data of slope stability and the slope survey suggestions; thereby, the survey suggestions for the slope can be determined; and based on the survey suggestions, it is determined whether to dispatch staff to conduct on-site surveys to ensure the stability of the slope, and before problems occur on the slope and before the slope monitoring system issues a warning, the slope is maintained to extend the service life, safety and stability of the slope.

[0087] It can be understood that the method of the present application is essentially a machine learning model, in which the stability of the slope is calculated to achieve continuous training of trainable parameters; wherein, the trainable parameters include a preset original stability value of the slope, a preset data comparison table, a preset first weight, a preset second weight, a preset third weight, a preset fourth weight, a preset fifth weight and a preset sixth weight, etc.; by training the above parameters, the calculation accuracy of the slope stability data is improved, thereby improving the accuracy of the slope stability assessment and improving the safety of the slope.
