中文摘要：

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。

英文摘要：

This paper presents an emergent best-practice process that is referred to as a（DIG）approach,in which a 4 dimensional（4D）engineering geological model can be developed for marine sites.This state-of-the-art approach integrates the geophysical data,geotechnical data and geological data（plus metocean data where necessary）in a Geographical Information System（GIS）environment.The 4 D model accounts for not only for 3D spatial variability of the seabed stratigraphy,but also temporally relevant geomorphological processes on the seabed,with time being the fourth dimension.The general principles are discussed first,followed by a case study demonstrating how DIG works in 4D and the engineering benefits this approach can offer.
