Regional geologic model non-redundancy updating method based on excavation record information

Abstract

The invention provides a regional geological model non-redundancy updating method based on excavation record information. The regional geological model non-redundancy updating method comprises the following steps: S1, creating an initial large-region geological information model; s2, creating an in-pit geologic model of the first project; s3, creating a foundation pit excavation body model of the first project; s4, creating a first project area model; s5, creating a large-area geological information model of updated data; s6, creating an in-pit geological model of updated data; s7, creating a foundation pit excavation body model comprising the first project and the newly added project; s8, updating the region model; and S9, continuously updating the regional geologic model under the multi-project background. The regional geologic model non-redundancy updating method based on excavation record information is beneficial to improving the problem of repeated processing of a multi-project foundation pit excavation model after new data of a large-region geologic information model is updated, and the processing and updating efficiency and quality of the geologic information model in a large-region development multi-project construction scene are improved.

Description

technical field [0001] The invention relates to the technical field of geological information models, in particular to a non-redundant updating method for regional geological models based on excavation record information. Background technique [0002] The development of underground space is the key content of urban and regional construction and sustainable development. A large number of deep, large and difficult urban underground space construction projects are increasing day by day. High concealment and high soil and water risks make urban underground space development and management difficult. At the same time, due to the lack of digital achievement management means of macro geological status information in urban areas and management, it is difficult to provide strong data support and decision support for later engineering construction, operation and maintenance and other links. [0003] In recent years, the rapid development of digital technologies represented by City Inf...

Problems solved by technology

[0004] However, under the background of multi-project construction of actual regional development, there are problems of staged creation and dynamic update of urban-level / large-region geological models, and there are certain limitations and deficiencies in the creation of conventional geological information models: The implementation of engineering survey is not completed at one time. After the new survey data is added to the regional survey database, the regional overall geological model needs to be re-interpolated and generated based on the updated database. There are frequent updates and creations, which brings large workload

(2) For the specific construction plots in the area, because they contain a lot of survey drilling data, the accuracy of the geological model does not change significantly during the dynamic update process, but in the follow-up process such as foundation pit excavation simulation, site condition analysis, etc. The process of construction and application brings the difficulty of repeated cutting and processing
