本文针对机场高填方工程复杂地质条件,分析研究了场址区域地质背景的典型特征,提出了相应地质背景特征量的计算算法并推导了相应计算公式。在此基础上,基于智能地质建模算法原理,建立了基于区域地质背景特征的地质智能建模方法,开发了相关的应用程序,实现了三维复杂地质模型的任意方向、任意断面的切割和地层显示。最后根据某工程场地地质勘察钻孔资料等成果,建立了该场地的三维地质模型,对该场地地质概况进行了全角度、不同分层、任意断面的展现,同时通过该地质模型和实际地质背景的对比分析,验证了该方法的实用性和可靠性。

In order to research the complex geological conditions of airport high fill engineering,the typical characteristics of the regional geological background are analyzed in this paper. The calculation algo-rithm of geological background is then proposed and the corresponding calculation formula is deduced. Onthis basis, the intelligent modeling method of regional geological background characteristics is built. Andthe relevant application procedure is developed, in which arbitrary direction and arbitrary section cuttingand formation shows of the complex three-dimensional geological model are realized. Finally, the boreholedata of a typical engineering is chosen to build the three dimensional geological model. And different showtypes of this model are given,including the whole angle,different stratification,arbitrary cross section. Asa result,the practicability and reliability of this method are proved through the contrastive analysis betweenthe geological model and the actual geological background.
