Abstract

The invention discloses a static sounding automatic soil layer division technology based on a pattern recognition technology, and relates to the technical field of soil layer division. The method comprises the following steps: sorting and analyzing static sounding data, and determining a training sample: collecting static sounding original data of an existing project, a corresponding layering result and comparable drilling data, and analyzing, screening, normalizing, standardizing and structurally sorting the static sounding original data, and sorting and normalizing and inputting the static sounding original data. According to the method, the model for automatically dividing the soil layer is trained based on the mode recognition technology, depiction and comparison of the static sounding curve form are fully grasped, the static sounding curve form serves as an important factor for dividing soil types, and the cone tip resistance, the side wall resistance and the friction resistance ratio in the static sounding data are combined, so that automatic soil layer division of the static sounding hole is achieved, and the accuracy of soil classification is improved. Therefore, the accuracy of automatic soil layer division through static sounding is greatly improved, the weighting coefficients of different types of data are added to improve the influence of important types, and the accuracy and reliability of stratum type recognition are further improved.

Description

technical field [0001] The invention relates to the technical field of soil layer division, in particular to a static penetration penetration automatic soil layer division technology based on pattern recognition technology. Background technique [0002] In geotechnical engineering investigation, the method of static penetration layering mainly depends on the engineer's engineering experience and drilling sampling data. The data collection frequency of penetration testing is generally 5-10cm / time, and the amount of data is relatively large. Therefore, the number of stratification results for each set of data is also huge, which results in too fine stratification to meet the requirements for stratigraphic division in actual engineering surveys. However, the existing technology must be supplemented by a large amount of manual merging work, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to provide a tech...
