本文展现了海洋工程地质领域一种新兴的数据整合方法。即会诊式地学数据整合(DIG)。此方法可广泛用于四维(4D)工程地质模型的建立。该方法利用地理信息系统(GIS)将物探数据、岩土工程勘察数据和地质资料(如有必要还可包括海况数据)整合为一个数据库并建立四维模型。此四维模型不仅可展现海床地层在三维空间的变化,还能揭示海床地貌随时间(第四维)的演变过程。论文首先讨论一般原理,然后通过一个实例演示如何使用此方法以及此方法可带来的工程效益。
This article presents an emerging approach to data integration in marine engineering geology. That is, clinics to learn data integration (DIG). This method can be widely used in the establishment of four-dimensional (4D) engineering geological models. The method utilizes Geographic Information System (GIS) to integrate geophysical data, geotechnical survey data and geological data (including sea state data where necessary) into a single database and to create a four-dimensional model. This four-dimensional model can not only show the changes of seabed strata in three-dimensional space, but also reveal the evolution of seabed geomorphology with time (fourth dimension). The paper first discusses the general principles, and then demonstrates how to use this method and the engineering benefits that this method can bring through an example.
