Abstract

The underground powerhouse cavern group of hydropower projects has the characteristics of large scale, complex geological structure conditions, and strong excavation disturbance. The analysis and evaluation of the surrounding rock quality are crucial for the stability, construction safety, and operation of the project. Therefore, this article takes a hydropower project as an example, based on geological modeling and attribute modeling BIM technology, establishes a comprehensive evaluation method for the surrounding rock quality of underground caverns that integrates geological, geophysical, and design multi professional and multi-source data, and uses three-dimensional geological modeling technology to establish the implementation methods of RMR, HC, and BQ three types of surrounding rock quality grading methods, realizing the visualization of surrounding rock quality grading and parameter values, quantitatively evaluating surrounding rock quality, significantly improving analysis efficiency, not only providing a new means for the classification of surrounding rock quality of large underground caverns, but also providing scientific basis for the design and construction of caverns, ensuring project safety, and having important project application value.
