Abstract
Gansu Province is a large province in Western China, and its geographical location and economic status are very important. With the state’s attention to the western development, the economy of the western region represented by Gansu Province has developed rapidly, and the construction of roads and other infrastructure has also been developed. Taking Gansu Province as an example, this paper studies and discusses the application of highway maintenance platform based on GIS + BIM Technology. Firstly, this paper expounds the advantages of GIS + BIM Technology in highway construction and maintenance, and analyzes the development status of GIS + BIM Technology; Secondly, it expounds how to solve the problem of highway maintenance from the aspects of GIS + BIM system and its advantages and difficulties in highway maintenance, and briefly explains the difficulties existing in highway maintenance in Gansu Province. Then, starting from the path of GIS + BIM Technology to solve highway maintenance in Gansu Province, this paper analyzes the expected effect of GIS + BIM Technology in highway maintenance in Gansu Province.
Highlights
Introduction toBIM + GIS System Platform TechnologyThe GIS + BIM application sub platform realizes the deep integration of GIS + BIM through data integration, system integration or application integration, gives full play to the respective advantages of BIM and GIS technology, realizes multi-dimensional highway engineering management from macro to micro, integrates engineering quality management, safety management, progress management, measurement management, operation management, maintenance management and other modules, and opens up business data.3.2

Summary
By the end of 2020, the highway mileage in Gansu Province will be 2.23 million kilometers, the expressway and first-class highway will exceed 6000 kilometers, the second-class highway and above will be nearly 17,000 kilometers, and the highway mileage will reach 192,000 kilometers (including natural village road). The backward management mode and ponding level have brought a significant negative impact on the management and maintenance of highways in Gansu Province. 1) The complexity of Geology and landform has a great impact on the accuracy of positioning and judgment of highways in the design stage, construction and later maintenance. Danxia landform is widely distributed in the area, with complex geological conditions and poor engineering geological conditions, which lead to many unforeseen factors in the safety control of highway management and maintenance construction in the later stage. 4. Logical and Physical Framework Design of BIM + GIS Applied to Highway Construction, Maintenance and Operation Management
