Embodiment Construction

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] This embodiment provides a construction monitoring method for simply supported variable structure continuous bridges, such as Figure 1~3 As shown, the method includes the following steps:

[0026] S1: Determine the influencing factors that have an impact on the simply supported variable structure construction, study their influencing laws, and establish an expert database of "dynamic variable field-structural behavior" with a learning function; the research on the laws includes: effective prediction of positive and negative bending moment areas; Influence law of stress; influence law of factors such as creep and temperature; determination of influence factors of structural system transformation and its influence law; other possible influence correction laws.

[0027] The determination of the influencing factors and the research on ...

Abstract

The invention relates to a method for monitoring continuous bridge construction with a simply-supported structure, and belongs to the field of civil engineering. The method comprises the following steps: S1, establishing an expert database; S2, establishing a whole construction phase growing BIM bridge structure model; S3, collecting and processing geometric data of a first construction phase completed bridge after the work condition of the first construction phase is completed so as to form an actually measured three-dimensional image of the phase; S4, performing deviation comparison on the actually measured three-dimensional image and the BIM bridge module to obtain a deviation control value; S5, inputting the deviation control value to the expert database, and feeding back constructioncontrol data; S6, completing next construction phase according to guidance of construction control data, and upgrading the expert database; and S7, automatically collecting real-time three-dimensionalimage of the bridge once again, and comparing with the whole construction phase growing BIM bridge structure model to form circulation. The method realizes visualized monitoring and controlling basedon the construction process.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a database-based visual monitoring and control system for a construction process, in particular to a construction monitoring method for a simply supported variable structure continuous bridge. Background technique [0002] Judging from the current distribution of bridge diseases, bridges with small and medium spans have far more diseases than bridges with long spans. The disease of bridges with small and medium spans largely depends on the construction quality, and the main application field of bridge monitoring is on long-span bridges, ignoring the construction monitoring of small and medium-span bridges. In the actual construction process of simply supported structure continuous girder bridges, there is a certain degree of randomness in the construction process due to the limitation of the natural environment and various practical conditions. The research on factors such as cree...
