Problems solved by technology

LEM is often chosen as the deterministic analysis method to evaluate the FS of slopes. The advantages of LEM are its simplicity and low computational cost, but its main disadvantages are: it is difficult to locate the critical sliding surface when the critical slip surface is not known in advance; moreover, The test sliding surface is usually assumed to be circular, which may not be suitable for complex slope systems, especially when the slope has weak interlayers

Embodiment Construction

[0072] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0073] refer to figure 1 , shows a flow chart of the steps of a method for calculating the failure probability of a slope system based on Kriging in the present application, which may specifically include the following steps:

[0074] Step S1: In the standard normal space, use the initial sampling point strategy to generate the training sample set of the slope system;

[0075] Reasonable selection of initial sample points can speed up the convergence of the training process. The initial training sample set can be constructed with Latin Hypercube Sampling (LHS), but this may not be suitable for some models with low probability of failure, since it must contain two classes of points (e.g., G(u) > 0 and G(...

Abstract

The invention provides a Kriging Kriging-based side slope system failure probability calculation method side slope system failure probability calculation method based on Kriging Kriging. An intensityreduction method SRM is proposed to evaluate the stability coefficient; an initial sampling point strategy and an active learning function are adopted; an active learning Kriging AK proxy model of anoriginal extreme state function LSF is constructed; the Monte Carlo simulation MCS and the AK agent model are combined to evaluate the failure probability of the slope system. According to the method,tThe influence of random variables and related parameters thereof on the slope stability can be quantified, the number of initial sample points is greatly reduced, the calculation efficiency is effectively improved, the sliding surface of any shape in the soil slope can be automatically recognized, and reliability analysis is more convenient when the layered slope with a complex geometrical shapeis subjected to reliability analysis.

Description

technical field [0001] This application relates to the field of stability analysis of soil slopes, in particular to a method for calculating failure probability of slope systems based on Kriging. Background technique [0002] Slope stability evaluation is a complicated geotechnical engineering problem, and its input parameters are uncertain. The traditional deterministic analysis method using the stability factor (FS) may not truly reflect the safety of the slope. In order to quantify the influence of uncertainty, probabilistic methods are widely used in slope reliability analysis. [0003] A slope may fail along different sliding surfaces, and the failure of any sliding surface will cause the failure of the slope, thus forming a series of system problems. Accurate and effective reliability analysis for such complex problems is the main problem facing the application of probabilistic methods in geotechnical engineering practice. [0004] The direct simulation method is a ...
