Research on Mechanical Characteristic of Weak Surrounding Rock Large Span Double and Multi-Arch Tunnel Construction
According to construction scheme of some weak surrounding rock large span double and multi-arch tunnel works, finite element value simulation method is adopted to research weak surrounding rock deformation characteristic, anchor bolt mechanics characteristic, preliminary support and secondary lining structure mechanical characteristics, etc, and the research result shows that: repeatedly distur...
متن کاملNumerical Analysis of Advanced Displacement in Construction Progress of Tunnel Excavation with Weak Surrounding Rock
Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-p...
متن کاملFinite Element Analysis of the Stability of Tunnel Surrounding Rock with Weak Rock Layer
The evaluation of local stability of the tunnel surrounding rock mass with weak rock layer is very important for the economy and security of the tunnel construction. Based on the rock tunnel geological conditions in the construction, the finite element model of the tunnel surrounding rock mass stability analysis with weak rock layer is established in the article by selecting the ABAQUS program ...
متن کاملResearch on Grey System Model and its Application on Displacement Prediction in Tunnel Surrounding Rock
In the process of the highway tunnel construction, the stability and the reliability of tunnel rock is an important guarantee to ensure safety construction. Tunnel surrounding rock deformation monitoring is an important method for obtaining information on surrounding rock and controlling tunnel stability in the period of construction. Forecasting deformation of surrounding rock is the key to es...
متن کاملDynamic Optimization Research on the Section Morphology of Large-span Tunnels in Shallow Rock Mass
The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...
