On the basis of Zhonghe Tunnel project An-Lan Expressway, objective this study was to determine appropriate method calculating steel arch load and stress release rate during numerical simulation. First all, based on monitoring results six similar tunnel sections where surrounding rock exerts pressure arch, using time functions, history curve could be fitted, two formulas for stable in deep tunnels were compared, calculation model suitable constructed. Then, a simulation performed Flac3D,...
With the rapid development of tunnel construction in China, deep buried and long projects are emerging areas with complex engineering geological conditions harsh environment, thus large deformation tunnels under high situ stress soft rock becomes increasingly prominent endangers safety. Therefore, it is great significance to control improve stability surrounding by analyzing thickness distribution law loose circle according unique mechanical properties failure mechanism soft‐rock tunnel....
Southern Shaanxi region is mountainous and landslide disasters are frequent. Micropile reinforcement technology widely used in management, especially emergency rescue projects, due to easy construction, small soil disturbance, strong site adaptability. Soil arch effect an important prerequisite for safe economic performance of the support function micropile. For swelling accumulation layer southern Shaanxi, firstly, a numerical model established by means thermal-mechanical coupling FLAC3D...
Abstract The plane strain apparatus is an important instrument for studying the strength and deformation characteristics of soil with a specific stress path under condition it indispensable theoretically rock mechanics. After reviewing summarizing development history apparatus, we improved pressure chamber, measuring mechanism, loading created chamber that can simulate state. This improvement was based on true triaxial vertical rigidity flexible in two orthogonal horizontal planes developed...
Based on the unified strength theory, elastic-plastic stress analysis is carried out under premise that first principal in two cases of radial and circumferential stress, formula radius surrounding rock plastic zone derived. Tunnel has three states which including elastic state, elastoplastic state maximum stress. When was tunnel, should be judged correct chosen to calculate. Analysis results show intermediate benefit give full play potential, so as improve stability tunnel smaller...
With regard to the excavation of coal mine tunnels, phenomenon roof separation frequently occurs owing deformation roadway surrounding rocks, and analysis influence rock on bolt reinforcement plays an indispensable role in security support engineering. In present paper, hyperbolic function model load transfer is simplified exponential form, distribution form modified by error analysis. Drawing analytic elastoplastic mechanics through separation, this paper further investigates development...
