Description

technical field [0001] The invention relates to engineering geological slope survey and design technology, in particular to a semi-quantitative automatic evaluation system for linear engineering (such as roads, railways, etc.) rock slope stability. Background technique [0002] In recent years, with the rapid development of engineering construction in mountainous areas (such as mountainous expressways), the scale of construction projects has been increasing, and the geological environment and technical issues involved have become more and more complex. The scale and complexity of slope engineering and the engineering cost have also been correspondingly At the same time, the qualitative evaluation of the stability of slope engineering has also received widespread attention from the academic and engineering circles. [0003] Today, for slopes with relatively isotropic homogeneous, continuous, and homogeneous materials such as soil, the analysis theory and calculation methods a...

Problems solved by technology

[0006] 1) Drawing efficiency is low and error-prone: Stereographic projection method drawing is mainly completed by technicians using paper and pen indoors. In recent years, computer design software is occasionally used to assist drawing. In recent years, with the construction of mountainous areas (such as With the rapid development of the mountainous expressway), the number of slopes along the line is often as many as dozens or even hundreds, involving multiple geomorphic units and lithologies. Each section of slope is different in size, scale, and type. Therefore, the workload of drawing is huge, which not only has the defects of long time consumption, low efficiency, and high labor cost, but also manual drawing is prone to errors, and it is difficult to meet the requirements of current engineering geological survey and design

[0007] 2) The failure mode of instability is not determined: the stereographic projection method does not make an analysis and judgment on the possible failure mode of instability caused by the unfavorable structural surface of the slope, so it is impossible to carry out accurate, effective and targeted quantitative calculations and take corresponding measures engineering measures

[0008] 3) High misjudgment rate: when the stereographic projection method is used for qualitative analysis, there are no quantitative indicators, and it is purely subjective judgment. Due to the different professional degrees and levels of technicians, the depth of understanding of the stereographic projection method is different. For the same slope, The results of different technicians' discrimination may be completely different, which is very easy to cause misjudgment, and once a misjudgment occurs, it may cause inestimable losses to the quality of the project

[0009] 4) The development of structural planes is not counted: For some rock slopes, the structural planes are complex (layers, joints, faults, schistographs, etc.) and the spatial distribution is complex, making it difficult for technicians to judge the structural planes. development, and whether it is the dominant structural plane of the slope

[0011] 6) Heavy workload, long time-consuming, and low efficiency: from the initial collection of first-hand surveying and mapping data to the sorting of surveying and mapping data, manually drawing maps for each slope, and then analyzing and judging each slope Evaluation and other work, and finally electronically form the results and send them to the hands of designers; such a large amount of work will take a long time to finally reach the hands of designers through the process of "data collation→manual drawing→analysis and evaluation→digitization". Affected work progress

[0012] 7) Difficulty in modification: Once an error occurs in the process and needs to be modified, it is necessary to re-draw, analyze and evaluate, which will undoubtedly increase the workload and lead to a lag in the work progress
