Abstract:
Objective It takes the profile of 3Dgeological modeling as principle for intersected modeling between tunneland strata,the paper presents a intersected modeling method between tunnel and strata.Taking the complexi-ty into account,intersected model is subdivided.It constructs the model of strata profiles within tunnel sec-tion,the intersected model among tunnel and strata profiles,and the intersected model between tunnel andstrata respectively.It is shown that the method of intersected modeling is feasible,ensures the spatial topolo-gical relations,and provides the reference for the relevant 3Dgeological modeling.
