Embodiment 1

[0035] A method for developing slope stability reliability analysis software under spatial variation characteristics, including the following implementation process:

[0036] Pre-processing analysis:

[0037] (1) Read relevant data used to calculate slope stability, including reading slope geometric profile data, soil material statistical data, soaking line position data or pore pressure data, and external load data. Among them, the slope profile data includes slope height, slope angle, number of soil layers, and the extension range of slope toe and slope top; soil material statistics include bulk density, cohesion, mean and standard deviation of internal friction angle, and characteristic soil The fluctuation range value of the degree of spatial variation characteristic of the layer parameter. Here you need to open a public array to save these data.

[0038] (2) The type of instability mode that assumes slope sliding, such as circular arc instability mode or non-circular ar...

Abstract

The invention belongs to the technical field of slope stability analysis software development and relates to a method for developing slope stability reliability analysis software under spatial variation characteristics. The method comprises the steps of on the basis of preprocessed data input, performing slope discretization and integration analysis to obtain a safety coefficient of a specific instability mode; performing a certain number of times of minimum safety coefficient search and determining main instability areas; finally realizing slope stability reliability analysis software development based on multiple main instability modes through the Monte Carlo sampling method. The method gives full consideration to system features brought by the spatial variation characteristics of soil mass materials, fills up the blank of system feature calculation caused by spatial variation characteristics in conventional commercial software, and has a high engineering application value and a good commercial prospect.

Description

technical field [0001] The invention belongs to the technical field of slope stability analysis software development, and relates to a method for developing slope stability reliability analysis software under spatial variation characteristics, in particular to a method based on limit equilibrium method to determine the response of slope system under spatial variation characteristics, and based on System Response Software Development Method for Slope Stability Reliability Analysis. Background technique [0002] Slope stability refers to the conditions and capabilities of natural or artificial slopes to maintain safety and stability. The rock and soil mass of these two types of slopes gradually change under the action of various internal and external factors, and the stress state of the slope body changes accordingly. Immediately, it will become damaged, causing disasters or threatening the safety of buildings. [0003] Slope stability reliability analysis is one of the most...
