Railway engineering construction organization image progress map automatic conflict checking method based on spatial analysis

Abstract

The invention discloses a railway engineering construction organization image progress map automatic conflict checking method based on spatial analysis. The method comprises the following steps: S1, designing bottom-layer geometric primitive drawing interfaces and a data storage structure and a semantic association relationship of construction organization plan items, designing a drawing method of each module of a construction organization image progress map, and realizing automatic generation of the construction organization image progress map; S2, dividing construction activity constraint relationships into time constraint and space constraint, and establishing a construction activity-space-time constraint two-tuple model according to the maximum and minimum space-time constraint relationships; S3, designing a visual expression mode of the space-time constraint model, and designing a linkage adjustment mode of the space-time constraint model in a time dimension according to dynamic adjustment requirements of a construction activity; and S4, performing automatic conflict checking and intelligent early warning on the construction organization plan items by using a GIS topological rule and a spatial analysis method. According to the method, the automation level and intuition are improved, and the accuracy and rationality of a construction progress plan are ensured.

Description

technical field [0001] The invention relates to the field of railway engineering construction, in particular to an automatic conflict checking method for a railway engineering construction organization image progress chart based on space analysis. Background technique [0002] Railway engineering construction has the characteristics of large scale, long construction period, complex process connection, frequent changes, etc. The construction schedule plan is interrelated and restrictive with construction quality, safety, and investment. Reflection is one of the core contents of railway construction project management. The "Code for Construction Organization Design of Railway Engineering" (Q / CR 9004-2018) promulgated and implemented in 2018 pointed out that in the construction of railway projects in my country, the construction unit must submit the construction progress plan, and the results must be reflected in the form of the construction organization image progress chart . ...
