Tunnel excavation in water-rich and saturated loess layers often encounters a series of engineering disasters, including surface settlement, large deformations surrounding rock, collapses, water inrushes, mud lining cracks. This paper presents an analogy 16 cases instability collapse rock during the tunnels China’s regions. The weight influence various factors affecting stability rocks has been analyzed based on Fuzzy Analytic Hierarchy Process (FAHP), addressing challenges encountered...
In order to study the effects of dry density and initial water content on permeability characteristics loess, saturated tests undisturbed loess remolded were carried out in Lanzhou New Area. The anisotropy under two factors is analyzed compared, difference between also analyzed. results show that structure has an important impact characteristics, structural parameter. natural obvious anisotropy. Under different pore conditions contents, it will anisotropic behavior permeability. influence...
In response to a series of engineering disasters encountered during the excavation and support construction loess tunnels, considering issues water enrichment in surrounding rock induced by disturbance system bolt failure, drawing on concepts lime pile composite foundation bearing arch, based principle New Austrian Tunneling Method (NATM) that fully mobilizes leverages self-supporting capacity rock, this study comprehensively considers wetting stress adjustment processes after tunnels. By...
In recent years, assisted reproductive technology (ART) has been widely used in clinical practice. With the growth of vitro fertilization and embryo transfer (IVF-ET) cycle numbers, improvement controlled ovarian stimulation scheme laboratory technology, resulted a large number surplus embryos during ART treatment. Many these are cryopreserved for long time by center, causing waste medical resources. The management disposition frozen face series legal ethical challenges. This study...
