摘要

对包含断层的复杂地质体三维构模技术展开讨论并提出相应的解决方案。分析了实际勘察所获取的断层数据类型，设计了标准的断层数据库格式；系统地评价了两类基本的断层构模方法（即基于地层恢复的断层构模技术和基于分区插值的断层构模技术），分析了各自的特点和不足，在此基础上提出了断层与地层的统一构模技术；该技术既能应用于同沉积断层，又能适应断层终止于地层内部的情况，还能处理具有多值面的逆断层构造的拟合问题，在理论上能够构造任意复杂的断层系统。通过北京奥运公园场址的断层构模实例验证了该方法的有效性。

Abstract

The simulation and expression of geological faults is an essential technique of the modeling approaches for the complex geologic bodies. The research domains of this paper are the basic theories and essential techniques of the structural modeling techniques of complex geological entities contained faults. The structural modeling techniques of complex geological entities contained reverse faults are discussed; and a series of approaches are proposed. Based on the practical geological exploration

data types that expressed geological faults in 3D are analyzed and a normative database format for geological faults is designed. Two kinds of modeling approaches for faults

such as modeling technique of fault based on stratum recover and based on interpolation in subareas

are compared. The Unified Modeling Technique for stratum and fault

a novel approach

is presented to solve the puzzled problems of reverse faults with multivalued surfaces

syn-sedimentary faults and faults terminated within geological models. In order to confirm the practical result of this method

a case study of fault model of bed rock in the Beijing Olympic Green District is presented.
