Problems solved by technology

[0004] At present, the review work of BIM design models is mainly based on manual review, which has the problems of low efficiency and high error rate
Civil3D itself can implement normative verification of road design, but it cannot automatically review BIM models in other fields including water conservancy
In addition, Civil3D itself is suitable for the overall creation of linear structures such as terrain and roads, and it is difficult to locally dynamically adjust and modify the gravity dam structure model
The existence of the above problems leads to low model accuracy, low efficiency and insufficient informatization of the created model

Abstract

The invention discloses a BIM-based gravity dam structure design compliance inspection method, which comprises the following steps of: establishing each section component of a gravity dam structure, and assembling along a dam axis to generate an initial BIM model of the gravity dam structure; creating a data access node packet and a data transmission node packet, exporting the initial BIM model parameter information and storing the initial BIM model parameter information in a database; establishing a material information base and a rule knowledge base of the gravity dam structure in the database; connecting the application program with the database and interacts with the database; and carrying out compliance check on the initial BIM model parameter information, giving an alarm if information which does not conform to related standard requirements exists, and carrying out modification according to related standard provisions. According to the method disclosed by the invention, the established gravity dam structure initial BIM model can realize compliance automatic check, so that the model precision and the model dynamic correction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic structure models, in particular to a method for checking the compliance of gravity dam structure design based on BIM. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is a digital model based on three-dimensional digital technology that integrates engineering entities and functions. With the rapid promotion of BIM technology in the field of civil engineering, its application in the construction of water conservancy projects is deepening, and the delivery of BIM models as design results is the development trend of the future design field. In the process of using BIM technology in the forward design of hydraulic structures, the accuracy and information contained in the BIM model are very important for the later model structure calculation and operation and maintenance analysis. Therefore, how to effectively implement the compliance check of the grav...
