中文摘要：

本文在分析GIS应用于工程勘察信息管理中可行性的基础上，设计了工程勘察信息管理系统的逻辑模型，并对其中关键技术和方法进行了介绍。以江苏省交通重点工程地质勘察信息管理系统为实例，介绍了系统的功能结构，提出应用多比例尺融合的方法对局部图层信息进行加密，解决了勘察钻孔的分散分布与背景图层信息量过大之间的矛盾，给工程勘察信息管理提供了一个有效、科学的技术手段。

英文摘要：

Based on the analysis of the feasibility for application of GIS to the information management of geotechnical investigation and surveying, the logical model flow chart of the management system is designed, and the key techniques used in the system are introduced. Taking the MIS of the key transportation engineering survey in Jiangsu province as an example, the structure and function of the system are discussed. In order to solve the conflict between the dispersion of exploration bores and the abundant information of background layers, the method of merging layers for different scale to dense the partial layer information is proposed, which provides an efficient and scientific tool for the information management of geotechnical investigation and surveying.
