With China's expanding economy, many tunnels are being designed and constructed. However, tunneling in hazardous geologic terrain, with faults, fractures, water-bearing openings, other adverse geological conditions, construction safety is seriously endangered. To ensure the of tunnel construction, a prospecting method was proposed applied at Xiangyun Tunnel Yunnan Province, China. In investigation stage, engineering hydrogeological conditions were analyzed to recognize high-risk sections....
The safety and efficiency of tunnel construction depend on the knowledge complex geologic conditions. Hence, an accurate forward-prospecting technique is required to detect unexpected inhomogeneous structures ahead construction. As method image heterogeneities, elastic reverse time migration (ERTM) introduced field forward prospecting. However, in environment, ERTM images may suffer from interference crosstalk artifacts, which are caused by converted waves surfaces. Therefore, considering...
Seismic forward-prospecting in tunnels is an important step to ensure excavation safety. Nowadays, most advanced imaging techniques seismic exploration involve calculating the solution of elastic wave equation a certain coordinate system. However, considering cylindrical geometry common tunnel body, Cartesian system seemingly has limited applicability forward-prospecting. To accurately simulate signal received tunnels, previous method using decoupled non-conversion extended from coordinates...
A model is developed for rarefied gas flow in long microtubes with different inlet-outlet pressure ratios at low Mach numbers. The accounts significant changes Knudsen number along the length of tube and therefore applicable to tubes encountering regimes length. Predictions from show good agreement experimental measurements mass rate, drop, inferred streamwise distribution obtained under conditions offer a better match experiments than do those conventional slip model.
The accurate prediction of the geological conditions ahead a tunnel plays an important role in construction. Among all forward prospecting methods, seismic detection method is widely applied. However, due to characteristics and complexity conditions, wavefield complicated. Carrying out more realistic modeling vital for fully understanding law wave propagation tunnel. In this paper, 3D staggered-grid finite-difference scheme cylindrical coordinate system based on decoupled nonconversion...
Abstract Objective To investigate the relationship between serum levels of lymphangiogenic factors and type 2 diabetic nephropathy to evaluate role lymphangiogenesis in nephropathy. Methods The patients were divided into a normal albuminuria group (UmAlb < 30 mg/24 h, n = 30), microalbuminuria 30–300 30) massive > 300 healthy individuals enrolled as control (n 30). Levels vascular endothelial growth factor-C (VEGF-C), factor-D (VEGF-D) chemokine ligand 12 (CXCL-12) quantified by...
