Abstract EN
During construction of 3D geological models, it is difficult to determine the uniform between geological model and true model.
As a comprehensive index, rock quality designation (RQD) is reliable to assess the rationality of geological models.
Unfortunately, The RQD of rockmass is determined completely by the deterministic threshold value and directions of the scan lines presently.
To avoid this drawback, the modified method of the RQD value based on the threshold value and 3D space is proposed in this paper.
Simultaneously, the analogue-simulation method based on rupture mechanism and classification of discontinuities is proposed.
The elliptical discontinuity is considered for general discontinuity, and the special discontinuities, such as bedding, fault, and interlayer are dealt with individually.
The accuracy of the 3D model is verified by the modified RQD.
The 3D model of the rockmass is analogue simulated through repetitively obtaining data from the interval confidence of geometrical parameters of discontinuities, which are determined by a mass of data derived from field investigation.
Besides, the dam base of the Xiangjiaba hydropower station is taken as an example, and the 3D model of the dam base is analog-simulated; its stability is evaluated by DDA method.
The safety coefficient of the dam base is obtained by utilizing the overload method.
