..., obtained equations express the deformation and the stress distribution of the geonet. INTRODUCTION Sand replacement on dredged and reclaimed marine clay has been used for some time. It is easy to construct the land on the soft clay, the replacement method dumping the sand into the reclaimed marine clay...

... movement and stress distribution must be reassessed for seam with deep dip angle. In view of this, based on field monitoring, model test and discrete element method are used in the study of strata behavior in inclined coal seam, relevant strata control method is proposed in the paper. MODEL TEST OF...

.... Consequently, the displacement of each crack and stress distribution around each crack are the same. An evaluation of the macroscopic strain field is possible by estimating the displacement distribution of a representative crack in the elemental region (Figure 2). COMPLIANCE OF THE MODEL In the model, the...

... broken coal with resin is analyzed. A circular area around a gallery could be injected. A material model is described for injected coal (Mohr-Coulomb envelope with a small cohe- Sion) and again an exact solution is found for the stress distribution and deforma- tions. Calculations show that only a small...

... 1.25 was modelled. This follows Sugawara et al. (1978) who concluded for a borehole cored with a thin walled bit, that the stress distribution in the basal region of the core is approximately constant for length to diameter ratios of 0.4 and greater (Figure 2) . For the case of a vertical borehole...
