BIM-based ventilation shaft construction schedule simulation and plan optimization

Abstract

In order to solve the problems of multiple construction links, mutual influence and restriction, and tight construction period of the ventilation shaft under complex geological conditions, the BIM technology is used to realize the three-dimensional parametric modeling of the Nanhu ventilation shaft project from geology, main structure and main construction equipment, etc. Simulating the construction schedule, formulating a reasonable schedule and optimizing the construction plan are of great significance for accelerating the construction schedule, controlling construction risks, and striving to make the Nanhu air shaft project put into use as soon as possible.
