Embodiment 1

[0125] In this embodiment, the applicant constructs a similar model slope according to the principle of similarity, and the model is constructed according to the ratio of 1:10, and the model is mainly similar to Figure 9 shown. The main content of its similarity theory is:

[0126] The similarity criteria of similar phenomena are equal, the similarity index is 1, and the individual parameters are also approximately 1;

[0127] In the case that the similar phenomenon is satisfied, the parameter relationship of the realization phenomenon can be converted into a functional relationship of the similarity criterion, which is the same as the functional formula of the similar phenomenon, also known as the π theorem, namely:

[0128] f(α 1 ,α 2 ,……α k ,α k+1 ,α k+2 ,...,α n )=0 (13)

[0129] F(π 1 , π 2 ,...,π n-k )=0 (14)

According to the method, the side slope seismic oscillation characteristics can be analyzed more accurately, the analysis method is simple, and the analysis efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of analysis of ground motion characteristics, in particular to a slope ground motion analysis method, device, equipment and readable storage medium. Background technique [0002] The seismic response characteristics of slopes have been one of the research hotspots in recent years. As a special and widely distributed type of slopes with weak interlayers, base-covered slopes have low elastic modulus and strength, so It often acts as a failure plane resulting in a lower degree of structural stability. It is not well applied in the seismic analysis of heterogeneous slopes. Contents of the invention [0003] The object of the present invention is to provide a slope ground motion characteristic analysis method, device, equipment and readable storage medium to improve the above problems. [0004] In order to achieve the above purpose, the embodiment of the present application provides the following tech...
