... 10 000 towns in France. We have studied the physico-mechanical behaviour and ageing of two types of chalk in underground quarries in the Parisian Basin, France. The dolomitic chalk (Saint-Martin-Le-Nœud) exhibits variations in mechanical and physical properties with horizontal pillar depth, and both...

... simultaneously. It is noted that the relative humidity variations at 1 mm above the top sur- face are quite good agreement with the drying-induced deformation behavior (Ohtake & Osada 2014). 3 TEST RESULTS In the following, a convention was adopted that shrink- age strain is negative and expansion is positive...

... (DFN) simulation results show some of the equations are suitable for calculation of mean trace length and the difference between actual value and their values is less than 15%. Apparent density is dependent on scale, but the Mauldon s estimators are independent of scale despite the variation...

Rainfalls are observed in spring and autumn and snow fall is observed during November till March remains on the ground till the end of the march (Fig. 8). Figure 9 shows the tempera- ture variation of rocks at certain depths. As noted from...
