Study On Arrangement Law Of Grouting Bolt In Mountain Tunnel, Zhao Licai
Study On Arrangement Law Of Grouting Bolt In Mountain Tunnel, Zhao Licai
Journal of China & Foreign Highway
In the sandy soil area with abundant water content, grouted bolts can solve the problems of poor stability of surrounding rock and groundwater erosion in tunnel construction. However, the unreasonable arrangement of grouted bolts will cause the waste of slurry and fail to achieve the predetermined grouting effect. Based on the differential equation of slurry diffusion, this paper realized the numerical simulation of grouted bolts in a tunnel through software secondary development. Combined with mathematical statistics, the influence of the distance of grouted bolts, tunnel radius, and grouting time on the formation of grouting rings in mountain tunnels was studied. …
Study On Parameter Optimization Of Feet‐Lock Anchor Pipes Of Tunnels In Unconsolidated Formation, Tang Heqing, Jiang Xishan, Yang Peng
Study On Parameter Optimization Of Feet‐Lock Anchor Pipes Of Tunnels In Unconsolidated Formation, Tang Heqing, Jiang Xishan, Yang Peng
Journal of China & Foreign Highway
In order to give full play to the supporting role of the feet-lock anchor pipe in the tunnel with unconsolidated formation, it is necessary to obtain the optimal construction parameters of the feet-lock anchor pipe. Based on a tunnel project on the Huaping–Lijiang Expressway in Yunnan Province, this paper conducted numerical simulation and field test analysis. By comparing the arch subsidence and horizontal convergence of the supporting structure when the feet-lock anchor pipe with different parameters was constructed, the paper explored the characteristics and causes of the influence of construction parameters on the feet-lock effect. The results show that the …

Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker
Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker
College of Graduate Studies: Theses & Dissertations
Author's abstract: Numerical simulation was used to investigate natural convection in horizontal and vertical enclosures with and without an internal heat source. Natural convection in rectangular enclosures is found in many real-world applications. Included in these applications are the energy efficient design of buildings, operation and safety of nuclear reactors, solar collector design, passive energy storage, heat transfer across multi-pane windows, thermo-electric refrigeration and heating devices, and the design-for-mitigation of optical distortion in large-scale laser systems. Considering all these applications, especially controlling heat transfer in nuclear power plants, knowledge and research results of natural convection in enclosure play a vital …
