摘要

为了建立结构规范统一的工程地质勘察信息数据库，提出了“用户”与“系统”两级数据库相互映射的技术，把用户对数据的操作和计算机处理数据的过程分离开来。其中用户数据库面向用户的需要，系统数据库则满足信息管理的要求。在系统数据库中采用“块—层”结构的地层数据模型，对钻探区域进行了“地层层序”优化。“块—层”模型把钻探区域的“优化地层层序”作为一个基本块，针对性强，层次清晰地表达了复杂多变的地层信息，将有不同地层层序的各个钻探点统一成相同的结构，解决了在地层模型中难以表达地层翻转、缺失信息的问题，极大地方便了后续的信息处理和钻孔数据插值的进行。

Abstract

In order to build a well-organized engineering geological information database

the exchange between users’ database and system database is put forward

by which the users’ operation and the procedure of computer are separated. The users’ database is users oriented

while the system database is for the management in the system. A new ground data model is proposed in the system database. This data model is about soil mass and a segment based on “the optimized stratigraphic sequence” of a region. By using it

complicated geological information can be expressed clearly; and drill holes of different stratigraphic sequences are united to a same structure. It can deal with some problems such as faults in the geological body

and make the subsequent management easy.
