Abstract

This invention provides a three-dimensional finite element non-blasting excavation numerical simulation method for rock mass excavation on waterway slopes. This method utilizes FORTRAN language code throughout the entire process to achieve 3D model mesh creation, excavation calculation, solution, and data visualization. By constructing a digital pre-simulation method using full-process code, it enables a forward-looking assessment of the matching between construction methods and rock mass conditions. Through multi-condition parametric simulation, such as different lithology combinations and excavation force combinations, this method can quantify the response of different construction methods to the rock mass under corresponding conditions. Based on the results, the calculation of parameters such as excavation efficiency and excavation volume can be further expanded.
