Abstract: Controlling rock mass uplifting is of great importance when grouting in large opening fracture with flowing groundwater. This paper investigated the basic mechanism of overburden stratum uplift. The ideal fluid assumption ...

Abstract: In the Jennings criterion, which is commonly used to estimate the shear strength of nonconsecutive jointed rock masses, the estimated values deviate from the actual values due to the criterion failure to consider the joint ...

Abstract: Soil-cement mixed piles are widely used to improve soft subsoil. But in regions with high-salinity groundwater, the soil-cement is susceptible to deterioration. At present, however, the design code for soil-cement pile ...

Abstract: Uniaxial compressive strength (UCS) and tensile strength are essential parameters of rocks, but the direct measurement of these two parameters is time-consuming and requires high-quality samples. As such, academics brought ...

Abstract: Tunnel construction in mountain areas, especially in karst regions, is challenging due to complex hydrogeological conditions in such regions, such as water inrush disaster induced by water-bearing structures that may ...

Abstract: In this study, a testing device was developed to analyze the characteristics of grouting diffusion in faults. To include the interaction of multiple grouting applications, tests consisting of four applications of grout ...

Abstract: Zonal disintegration around a deep excavated tunnel is a characteristic of the rock mass intense fracturing phenomenon. In this paper, three-dimensional numerical tests on the failure processes of rock samples containing ...
