Example Embodiment

[0029] In order to solve the disadvantages of inaccurate results and greater subjective arbitrariness caused by the inaccurate results and greater subjective arbitrariness caused by the inaccurate results and greater subjective arbitrariness in the evaluation and determination of the stability of the dangerous rock masses of environmental slopes, the present invention provides an on-site survey. A matrix evaluation construction method that can more accurately determine the stability of environmental slope dangerous rock masses combined with theoretical calculations. The matrix evaluation construction method includes the following steps:

[0030] a. Establish identification indicators, and determine the degree of impact on the stability of the dangerous rock mass of the environmental slope by qualitatively judging the engineering geology, and determine at least the terrain slope code is A1, the rock structure code is A2, the formation lithology code is A3, and the structure The un...

Abstract

The invention discloses a matrix evaluation construction method for determining the stability of environmental slope dangerous rock mass, and belongs to the technical field of infrastructure designing and building of constructional engineering. The matrix evaluation construction method can be used for accurately determining the stability of the environmental slope dangerous rock mass through combination of field investigation and theoretical calculation. The matrix evaluation construction method includes the steps that firstly a designer builds environmental slope dangerous rock mass identification indexes, and field investigation personnel are made to perform field investigation and record on a field; secondly, various parameters are submitted to the designer, a multifactor interaction relation matrix formula is formed by the adoption of the A.L.saaty scale numerical method, weighted values of the main identification indexes are worked out according to the formula, and the main identification indexes are determined; finally, contribution value assignment is performed on the main identification indexes, the total value of the evaluated environmental slope dangerous rock mass is worked out through the calculation formula, and accordingly the stability of the environmental slope dangerous rock mass is judged.

Description

technical field [0001] The invention relates to a matrix evaluation construction method, in particular to a matrix evaluation construction method for determining the stability of an environmental slope dangerous rock mass, and belongs to the technical field of construction engineering infrastructure design and construction. Background technique [0002] With the continuous construction of construction projects, especially water conservancy and hydropower projects, the safety of environmental slopes outside the project opening line has become increasingly prominent, and it is particularly necessary to carry out targeted investigation and stability evaluation of dangerous rock masses in environmental slopes. Dangerous rock masses on environmental slopes are generally steep, and sometimes it is difficult for surveyors to reach them. The stability evaluation methods are often different from those of the main project. They are generally based on geological surveys and qualitative ...
