Abstract
Aiming at the problems of low efficiency in creating and applying BIM models for slanting-cut tunnel portals and dependence on existing modeling platforms for visualization,this paper proposes a WebGL-based digital modeling method.This paper analyzes and summarizes the basic structural composition and characteristics of slanting-cut tunnel portal,and establishes the parametric BIM model for slanting-cut tunnel portal by using mathematical formulas based on the solid generation theory of point-line-plane-solid;realizes online browsing of BIM model for slanting-cut tunnel portal relying on WebGL technology.At the same time,this paper studies the auxiliary construction method of BIM model for slanting-cut tunnel portal,and expands the engineering application scenario of BIM model for slanting-cut tunnel portal.The results show that this method can assist designers to efficiently complete the forward design of slanting-cut tunnel portal and improve the creation efficiency and practicability of BIM model for slanting-cut tunnel portal.
