Problems solved by technology

For tunnels that exceed the design standards, the construction process will inevitably produce a lot of unnecessary manpower and material resources.
For tunnels that do not meet the design standards, they must be repaired at the end of the construction. Considering the particularity of tunnel construction, repairing the completed tunnels will not only consume a lot of manpower and material resources, but may also contribute to the safety and stability of the tunnel. Sex leaves a hidden danger

Abstract

The invention discloses an intelligent selection and optimization method and system for tunnel excavation and support parameters. The method comprises the steps that surrounding rock identification before construction is conducted according to geological data before construction, and primary excavation and supporting parameters are determined based on the surrounding rock identification result; then, based on primary excavation and supporting parameter construction, real-time surrounding rock identification is carried out in combination with geological data collected in the construction process; and the current surrounding rock identification result is compared with the previous surrounding rock identification result, and the excavation and support parameters are optimized according to thecomparison result. According to the method and system, excavation and support parameters of tunnel construction can be optimized, unnecessary manpower and material resource consumption in the tunnelconstruction process is avoided, it is guaranteed that the tunnel construction result more accurately meets the design standard, and the situation that deformation and instability occur after a tunnelis built is avoided.

Description

technical field [0001] The invention relates to the field of tunnel design engineering, in particular to an intelligent selection and optimization method and system for tunnel excavation and support parameters. Background technique [0002] In the field of tunnel engineering, each tunnel has its corresponding design standards, such as tunnel boundaries, tunnel stability, etc. The ultimate goal of tunnel construction is to construct a tunnel that can meet the design standards. [0003] Under the current technical environment, tunnel engineering is usually carried out according to the excavation and support parameters designed and formulated according to the exploration results of the construction environment and the tunnel design standards before construction, and according to the established excavation and support parameters during construction. parameters for construction. However, due to the complexity of the geological environment, there may be many errors and omissions...
