The contribution of geostatistics to the characterisation of some bimrock properties

Investigation of scale effect of numerical unconfined compression strengths of virtual colluvial–deluvial soil–rock mixture

“…The 2D image process was then be utilized to isolating the blocks from the matrix through numerical codes [19,31]. The image process primarily consists of pretreatment and segmentation procedures.…”

“…As for the 3D sieving method, it can be easily performed at the laboratory scale, but for larger volumes it becomes cumbersome and very expensive. Moreover, this technique is unable to investigate the morphological and spatial variability of this geo-material [19]. Consequently, although the 2D image process technology has its limitations, it is a relatively fast, non-destructive and inexpensive method for extracting and studying the morphological properties of SRM.…”

“…Direct observations by means of laboratory experiments [6,7,[15][16][17]21,22,24,29], and in-situ mechanical experiments [1,4,18,30] have provided a great deal of insights into the complicated geo-mechanical behaviors of SRM. In summary, volumetric block proportion (VBP) has the most remarkable influence on the overall strength and deformational modulus of mélange [6,7], Ankara Agglomerate [15][16][17], rock and soil aggregate [1,30] and shale-limestone chaotic complex bimrock [19].…”

“…With respect to study-A, several methods can be employed for characterizing the block inclusions, involving the one-dimensional (1D) scanlines (boreholes) method [8,9], the two-dimensional (2D) image process technology [19,31,32], as well as the threedimensional (3D) sieving method. The 1D scanlines (boreholes) method and the 2D image process technology can be utilized as equivalent of the volumetric proportion of brock inclusions according to the law of stereology [14].…”

“…The studies on the aforementioned geo-materials can be summarized primarily based on two categories including the inherent attributes of the geo-material (study-A) [8][9][10][11]28,36], and the geo-mechanical response subject to various external driving forces (study-B) [1][2][3][4][6][7][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][29][30][31][32][33][34].…”
