Embodiment 1
[0131]The purpose of the present invention is to provide a comprehensive intelligent soil layer classification technology based on machine learning for the static penetration test, and to provide a new direction for domestic research on soil layer identification in the static penetration test.
[0132] The method of the present invention mainly includes two parts: training machine learning model and using machine learning model, wherein the part of training machine learning model needs to use artificial layered static penetration test data to obtain the soil layer classification model including artificial experience, and use The machine learning model part no longer requires manual participation, and the results of soil layer classification can be obtained by directly putting the original data of the static penetration test into the machine learning model. The block diagram is as Figure 4 As shown, the specific method includes the following steps:

[0173] 1. Implementation case
[0174] Implementation case Taking a substation engineering base as the research area, a total of 25 static penetration test drilling points were selected. The relative positions of the 25 points are as follows: image 3shown. Among them, select {1C1, 1C4, 1C5, 1C6, 1S5, 1S7, 1S9, 1S20, 1S22, 1S26, 1S28, 1S29, 1S33, 1S34, 1S35, 1S36, 1S37, 1S39, 1S40, 1S42, 1S44} with a total of 21 points The static penetration test data is the training data set, and the data of four points {1C2, 1C3, 1S43, 1S45} are the test data set. Some sample data are shown in Table 1.
