Method for planning and organizing traffic in water conservancy and hydropower station based on live-action modeling and BIM

Abstract

The invention discloses a method for planning and organizing traffic in a water conservancy and hydropower station based on live-action modeling and BIM. The method comprises the following steps: 1, constructing a site excavation three-dimensional model; 2, carrying out fine subdivision processing and planning partition on the excavation model in combination with a construction organization design scheme; 3, organizing an intra-site transportation route preliminary scheme in combination with partition and site conditions; 4, simulating an excavation transfer process based on BIM software, and sorting and analyzing the road transportation intensity; 5, evaluating the reasonability of the scheme by adopting a Delphi method; 6, adjusting the design scheme; and 7, sorting simulation results to form a road transportation strength database. According to the invention, the problems of insufficient line function coordination and the like existing in the existing intra-site traffic planning organization and road design are solved; the method has the advantages of accurately simulating the transfer strength and engineering quantity of each subarea, improving the rationality of an intra-field traffic planning organization scheme and reducing the risk of engineering investment increase.

Description

technical field [0001] The present invention relates to the technical field of traffic organization in water conservancy and hydropower projects. Specifically, it is a method for planning and organizing traffic in water conservancy and hydropower projects based on real scene modeling and BIM. More specifically, it is a method based on real scene-BIM coupling. With the support of models and BIM software, it is a technical method for quickly planning and organizing traffic schemes in the field. In the present invention, the real scene modeling model is a BIM model that includes terrain, images and design boundaries of real scenes. Background technique [0002] The intra-site traffic of water conservancy and hydropower projects is the traffic between the various work areas, stockyards, stockyards and various production and living areas within the construction site. The task of on-site traffic planning is to correctly select the routes of main transport and auxiliary transport m...
