Embodiment Construction

[0041] The present invention is further illustrated below by way of examples.

[0042] Section k68+890~+990 of the 14th standard of a highway in Yunnan under construction is located in the transition zone between the Yunnan-Guizhou Plateau and Sichuan. Risk assessment is carried out according to the aforementioned theoretical framework.

[0043] 1. Risk fuzzy comprehensive evaluation

[0044] (1) Geological factors

[0045] There are no faults in the landslide body, and two sets of joints are developed in the oblique bedding. There is a relatively steep facing surface in the lower part of the landslide, and the slope of the front facing surface is above 60°. , the lithology is purple-red, purple-gray medium-thick layered mudstone, the mudstone is fully-severely weathered, the fully-weathered mudstone is clay-like, the strong-weathered mudstone is gravel-like, the gravel is massive, and the local fully-weathered mudstone is Bulk structure.

[0046] (2) Structural factors

Abstract

The invention relates to a mountainous area highway landslide risk evaluation model. The method is based on the theory of fuzzy mathematics, uses fuzzy comprehensive evaluation method, Delphi method, analytic hierarchy process and other methods to calculate the membership influencing hazard and vulnerability of highway side slope so as to obtain index evaluation level of hazard and vulnerability of slide slope risk, on the basis, adopts method of risk evaluation matrix to carry out risk evaluation of talus side slope. The model can predict, recognize, assess and analyze the slide slope risk of side slope that is possible to meet, and on the basis effectively cope with the risk to avoid or reduce the hazard of landslide geological disaster on national economy and life and property of people, and can take measures such as corresponding prevention and treatment on the basis of judgment and prediction of development and change trend of the landslide body.

Description

technical field [0001] The invention relates to a landslide risk assessment model for expressways in mountainous areas. Background technique [0002] Landslide disaster is a part of the natural environment, and it is a serious natural disaster second only to earthquake disaster and flood disaster. The harm of landslides to the development of human society and economic construction is worldwide, and the economic losses caused by landslide disasters to countries all over the world are estimated to reach billions of dollars every year. The horizontal and longitudinal sections of expressways in mountainous areas have high indexes, and it is inevitable to fill and excavate the mountain body during the construction process, so the density of landslides is high and the frequency is high. In addition, in the construction of expressway projects, if due to landslides, the project cannot be brought into full play in time or its use is interrupted, the indirect losses will be even grea...
