Digital data processing method of stress and strain for reinforcement of broken and weak surrounding rock face

Abstract

The present invention provides a stress-strain digital data processing method for strengthening the face of broken and weak surrounding rock, including: S100 establishes a three-dimensional model of the face of broken and weak surrounding rock according to the project design, and performs virtual finite element segmentation to form the face of the face 3D finite element model; S200 detects and saves the basic data of the surrounding rock face during section excavation; S300 combines basic data and 3D finite element Adhesive repair demand strength of the rock face; S400 selects reinforcement measures for the surrounding rock face according to the adhesive repair demand strength, and introduces the reinforcement measures into the 3D finite element model for effectiveness analysis. This method can improve the analysis efficiency and effectiveness of the stress-strain data of the broken and weak surrounding rock face reinforcement, improve the analysis accuracy, and guide the reinforcement of the surrounding rock, which can ensure the reinforcement effect, avoid reinforcement failure, and control the reinforcement cost of the surrounding rock.

Description

technical field [0001] The invention relates to the technical field of surrounding rock reinforcement stress data processing, in particular to a digital data processing method for stress and strain reinforcement of broken and weak surrounding rock faces. Background technique [0002] In the tunnel construction under the geological condition of broken and weak surrounding rock, one of the most prominent problems in the construction process of the tunnel with weak surrounding rock is the stability of the tunnel face. In order to maintain the stability of the tunnel face, it is often necessary to strengthen the tunnel face. However, if the reinforcement measures are not in place, it will not only endanger the construction safety, but even affect the operation safety. The reinforcement method can adopt advanced pre-reinforcement technology, use pipe shed and / or anchor rods, improve the strength of broken and weak strata and the stability of surrounding rock, and ensure safety. ...

Problems solved by technology

[0003] However, the reinforcement effect of the face of the surrounding rock requires data support. At present, the analysis of the stress-strain data of the face of the surrounding rock is often done manually and judged, which is time-consuming and laborious, and it is difficult to guarantee the correctness of the calculation results. The accuracy of the stress-strain analysis of surrounding rock reinforcement will cause adverse consequences of reducing the reinforcement effect and affecting the stability of the face
