With the development of Caofeidian industrial district in Tangshan recent years,geological data of the site are required for the construction of infrastructure construction projects. Although the site geological conditions of each project are different from each other and individual geological explorations are needed,there are many comon characteristics of soil horizons in macroscopic aspect in a region at all times. A construction project will be benefited in its early stage before specific exploration is executed by analyzing and comparing the characteristics of regional geological data from conducted geological explorations and building the sequences of regional soil horizons. It is attempted in this paper to compare and analyze the data of geological exploration finished in this area and to study the characteristics of soil horizons and build preliminarily the sequences of regional soil horizons. The conclusions can be applied and referred to in feasibility study,engineering exploration,design,construction for other follow-up projects in their early stage in this area.%本文试图通过比较、分析近年来曹妃甸工业区几个已建工程的地质勘察资料，找出其中的一些规律并基本建立这个地区的地层序列，使后续的其它工程建设项目的勘察、设计工程师对这个地区的地层有一个总的了解，为后续建设项目的可行性研究、勘察、设计、施工等提供前期参考。
