Static cone penetration soil layer division method and system based on multi-layer perceptron

Abstract

The invention provides a static sounding soil layer division method based on a multi-layer perceptron. The static sounding soil layer division method comprises the following steps: acquiring static sounding data; obtaining a soil layer division result according to the obtained static sounding data and the multi-layer perceptron model; based on the soil layer division result, performing intra-layer data processing and interlayer data processing to obtain a final soil layer division result; according to the method, a multi-layer perceptron model is combined, soil property and mechanical property layering are integrated, focus of attention and engineering experience of geotechnical engineering are internalized into a system, and a high-precision soil layer division result which can be directly applied to engineering practice is formed.

Description

Technical field [0001] The present invention relates to the field of data processing technology, particularly to a statically tactile soil layer division method and system based on a multilayer perceptron. Background [0002] The statements in this section merely provide background techniques related to the present invention and do not necessarily constitute prior art. [0003] As a practical in situ test method, static penetration (CPT) has been widely used in the field of geotechnical engineering with its advantages of simple equipment, convenient operation, good continuity, reliable data, high repetition rate and wide application range. The use of static penetration parameters to determine the mechanical parameters of rock and soil is an important application of static exploration in geotechnical engineering. [0004] In geotechnical exploration, static tactile soil identification and stratigraphic division mostly rely on the engineer's engineering experience and drilling sam...

Problems solved by technology

Because the layering of the above method is too detailed and often cannot meet the actual engineering needs, and the regression equation is affected by the reliability of the static penetration parameters used in the classification and identification of soil properties, the formation environment and regression analysis, it has strong limitations. In engineering practice Difficult to be widely used in

[0005] The inventors found that in geotechnical engineering investigation, not only the type of soil should be considered in stratum division, but also the mechanical properties of the soil layer are also important considerations; the existing classification and layering methods focus on the division of soil types, and the Less attention has been paid to the mechanical properties, which also caused the delamination results to be unsatisfactory
