Embodiment Construction

[0029] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The present invention aims at distributing two or more kinds of altered rock masses in altered rocks (belts), and various alteration types of rock masses have certain mechanical differences and are distributed in the form of "coupling, mixing, and wrapping". To solve the problem of the method for selecting the comprehensive deformation modulus parameters of composite altered rocks (belts), a method for obtaining the comprehensive deformation modulus parameters of specific composite altered rocks is provided, such as figure 1 As shown, the specific steps of this method are as follows: firstly, investigate and test the macroscopic geological characteristics of the altered rock / zone, the macroscopic mechanical properties and petrological characteristics of each altered rock mass inside; Mineral composition, composition and conten...

Abstract

The invention relates to the fields of rock soil and water-power engineering, and provides a specific compound alterated rock/zone comprehensive deformation modulus parameter acquisition method to solve the problem of no specific compound alterated rock/zone comprehensive deformation modulus parameter acquisition methods at present. The method concretely comprises the following steps: investigating and testing the macroscopic geological characteristics, the internal alterated rock macroscopic mechanical properties and the petrologic characteristics of an alterated rock/zone, and dividing the concrete alterated rock/zone according to the alteration type; carrying out deformation test on all alterated rocks in all the alteration types of areas to obtain the corresponding deformation modulus of every alteration type rock in every divided area; and calculating according to the corresponding deformation modulus of every alteration type rock in every divided area and the area of every alteration type rock area to obtain a compound alterated rock/zone comprehensive deformation modulus parameter. The method is suitable for acquiring the rock comprehensive deformation modulus parameter.

Description

technical field [0001] The invention relates to the field of geotechnical and hydropower engineering, in particular to a method for obtaining comprehensive deformation modulus parameters of composite altered rocks (belts) with multiple altered types of rock mass. Background technique [0002] Altered rocks refer to rocks formed by secondary changes in rocks and minerals caused by hydrothermal, supergenetic and tectonic processes. Alteration changes the physical properties of the primary rock mass by changing some of the mineral components, structural types, etc. inside the rock mass. The difference in mechanical properties and alteration will cause uneven rock mass properties, and even form geological defects such as engineering weak zones. For a long time, the research on altered rocks has been mainly used in ore deposit geology, mainly through the characteristics of altered rocks to study the quality, quantity, distribution and formation mechanism of related ore-forming mi...
