Method for constructing three-dimensional digital information management system of earth-rock aggregate tunnel

Abstract

The invention relates to a method for constructing a three-dimensional digital information management system of an earth-rock aggregate tunnel, and belongs to the field of civil engineering. The method comprises the following steps: S1, inputting information, namely inputting section photos, the section basic condition and construction support parameters by the constructing personnel, inputting measurement data by the measurement personnel, and inputting management scores and control standards by the management personnel; S2, data processing: firstly, obtaining a section picture digital image;secondly, carrying out data measurement and regression analysis; and finally, achieving the intelligent classification of the surrounding rock and the intelligent auxiliary design of the supporting;S3, carrying out the visual output: firstly, realizing the integration of the cross section geology, the monitoring and the supporting information; secondly, carrying out the construction, monitoringgrading and management; finally, realizing three-dimensional digital informatization through combining the section mileage; S4, designing an intelligent tunnel: based on the result of the step S2 andthe result of the step S3, carrying out the tunnel intelligent auxiliary design. According to the invention, the digital information integration of tunnel construction can be realized. Therefore, theobjective, safe, efficient and intelligent design, construction and management of the earth-rock aggregate tunnel are achieved.

Description

technical field [0001] The invention belongs to the field of rock and soil tests, and relates to a method for constructing a three-dimensional digital information management system of an earth-rock mixture tunnel. Background technique [0002] Tunneling through deep soil-rock mixture areas is a new engineering geological problem that has emerged in the development of mountainous cities and towns in recent years. There is a lack of similar engineering experience, and due to the heterogeneity of soil-rock mixture, temporal and spatial variability, and extreme physical property differences between soil and rock , making the construction design of the tunnel engineering through the earth-rock mixture extremely difficult. At the same time, in the actual tunnel construction, the construction management department overall controls the project quality, the on-site construction department is responsible for the specific construction support, and the monitoring and measurement departm...

Problems solved by technology

[0005]Because the earth-rock mixture tunnel is a new type of engineering geological problem in the current urbanization process, there is currently a lack of similar engineering experience

At the same time, due to the strong temporal and spatial variability of the soil-rock mixture, as well as the complex and changeable particle size composition of the rocks and the properties of the matrix soil, it is difficult for the construction management department, the on-site construction department, and the monitoring and measurement department to communicate in real time and efficiently. Accurate classification of surrounding rock, and then safe, reliable, reasonable and economical tunnel construction design

[0006] 2. Conventional tunnel information management system is difficult to obtain accurate geological information o
