Multi-source data standardization processing method integrated with engineering geological achievements

Abstract

The invention discloses a multi-source data standardized processing method integrated with engineering geological achievements. The method comprises the following steps of: formulating a standard stratum table compatible with a surrounding urban stratum division standard; geographically correcting the exploration point distribution map by utilizing the high-precision ortho-image map, and quickly obtaining the accurate coordinates of the drill hole on the premise of not depending on field surveying and mapping. By means of formulating a stratum comparison table for each geotechnical engineeringinvestigation report, automatic and batched stratum standardization processing is achieved. The ortho-image map, a digital elevation model, a surface three-dimensional model, an underground pipelinemodel, an underground building model and an engineering geological result are combined, and the effect of three-dimensional integrated management on the ground and underground is truly achieved. Project verification shows that the method has the advantages of being high in data collection and arrangement speed, high in stratum division standard applicability, complete in integrated data type and the like, the management level of engineering geological achievements is effectively improved, and the method has great significance in the fields of urban planning, engineering site selection, disaster prevention and the like.

Problems solved by technology

In order to solve the problems of scattered data storage, paper-based media, and inconsistent standards, some cities have successively built engineering geological information systems, aiming to realize the standardization and information management of engineering geological achievements.

Problems existing in the existing technology: 1. The stratigraphic division standard is only applicable to this region, lacks transition compatibility with surrounding cities, and is not conducive to cross-regional data integration; 2. For engineering geological data with unknown coordinate systems, a large number of field workers are required. Supplementary measurement of borehole coordinates has greatly affected the efficiency of data collection and arrangement; 3. When managing engineering geological achievements, the types of integrated data are not comprehensive enough, especially the lack of support for emerging data such as urban 3D models
