Abstract Multi-scale 3D geological modeling technology is a vital issue to illustrate the complex conditions of infrastructure projects at regional scale, engineering and outcrop scale. It also computational basis for numerical geotechnics seepage stabilization studies. However, empirical interactive methods based on expert knowledge are mostly applied in existing researches structures different scales modeled independently, which reduces credibility simulation. Therefore, this research states fusion method multi-scale structures: (1) The multi-constraint NURBS multi-valued strata scale discrete fracture network discontinuities presented. (2) subdivision-NURBS multiple genera bodies raised so that genus characteristics can be expressed an objective parameterized way rather than interactive-modeling way. (3) Enhanced Boolean Logic Sequences Oriented Geological Interfaces (E-BLSOGI), where additionally introduced BLSOGI offered authors’ previous study [1], provided achieve structures. practice indicates realized, evidencing results without integrating underestimate compressive stress (16.37, 10.52, 33.09%), tensile (16.57, 21.57, 10.76%), displacement (7.17, 47.62, 33.62%) dam foundation x -, y z-, directions, respectively.
