摘　　要：地质勘察是水利水电工程建设中的基础性工作。传统的地质勘察依赖于纸质材料记录地质信息,导致二维图件的直观性较差且极易丢失空间特征,现场分析过程大量依赖主观经验,内外业工作脱节难以保证编录效率及数据的可靠性。本文基于三维实景技术、地理信息系统(Geographic Information System,GIS)、机器学习算法、地质建模等技术方法,提出了以多源数据融合、多平台协同与二三维联动、地质智能编录及快速空间解译为核心的水工地质数字化编录与内外业一体化分析方法,并研发了适用于桌面端和移动端的软件平台,包括三个主要模块:①底图模块:基于多源数据而构建融合的三维实景,实现数据的多平台协同及二三维联动,为内外业工作提供参考场景。②编录模块:基于多平台协同和智能识别方法,实现地质点、地质界线和勘探对象的编录。③分析模块:基于空间解译方法,实现空间产状面的推求和三维空间交线推断等。在具体功能上,移动端侧重外业采集,桌面端侧重内业分析,二者相互配合实现内外业工作的无缝衔接。该系统平台已应用于我国西部一座水利水电工程的地质勘察工作中,与传统工作模式进行对比,大幅提高了地质勘察编录与分析的效率和质量,可为其他类似系统提供可借鉴的方法和模式。Geological investigation is a basic work in hydraulic project construction.The traditional geological survey records geological information on paper.However,this leads to a poor intuitiveness of the two-dimensional map and even a loss of its spatial features,and the field analysis process has to rely on subjective experiences heavily;disconnection of office work from field work makes it difficult to ensure data recording and analysis efficiency or data reliability.This paper presents an integrated method of 3D real scene recording and office-field analysis for hydraulic engineering geology.This system is based on the 3D real scene technology,Geographic Information System(GIS),machine learning algorithm,and geological modeling,focusing on the development of multi-source data fusion,multiplatform collaboration and 2D and 3D linkage,geological intelligence recording,and fast spatial interpretation.We develop two sets of platforms suitable for desktop and mobile terminals,including three main modules:1)A base map module constructs a fused 3D reality using multi-source data and achieves multi-platform collaboration as well as 2D and 3D linkage of data,thereby providing reference scenes for office work and field work;2)A recording module adopts a multi-platform collaboration and intelligent recognition method to implement the recording of geological points,geological boundaries,and exploration objects;3)An analysis module,based on spatial interpretation,calculates spatial occurrence planes and makes inference about three-dimensional spatial intersection lines.In terms of specific functions,the mobile terminal focuses on field acquisition,while the desktop terminal on indoor analysis;both cooperate to achieve a seamless connection between office work and field work.The system has been applied to the geological survey of a hydraulic project in western China,and it shows a significant improvement on geological recording efficiency and quality in comparison with the traditional survey.
