Description

technical field [0001] The present invention relates to the field of three-dimensional visualization of tunnel and surrounding rock mass models, and more specifically relates to a method for quickly constructing an interactive three-dimensional model of tunnel and surrounding rock mass, which is suitable for rapid reconstruction of accurate tunnel and surrounding rock mass models in the field of tunnel simulation or tunnel digital design. structure. Background technique [0002] Generally, engineering construction requires large investment, long period, and high risk, especially when it involves tunnels, because of the complexity of the geological environment it depends on and the high error of prediction, and it has permanent characteristics during the service period, and cannot be modified once it is completed. Accurately grasping the three-dimensional stratum information where the tunnel is located in the design stage can propose a more optimized tunnel design scheme, red...

AI Technical Summary

Problems solved by technology

[0003] At present, the models of the tunnel and its surrounding rock mass involved in tunnel simulation and digital design are generally modeled manually, which has a long modeling cycle and difficult to guarantee the accuracy of the model.

When the tunnel design scheme changes, the involved tunnel and surrounding rock models need to be reconstructed, and the manual modeling method cannot meet the real-time requirements of tunnel simulation and digital design

In surrounding rock modeling, only geological drilling data are generally used, and formation profile information cannot be effectively used. It is difficult to accurately describe the surrounding rock structure, and it cannot meet the accuracy requirements of tunnel simulation and digital design.

At present, there are technical problems in the field of tunnel simulation and digital design, such as long modeling work cycle, low precision, large amount of manual editing, and efficient interaction of tunnels passing through surrounding rocks.
