چکیده
Highway tunnel group has the characteristics of large span and small spacing, load distribution surrounding rock between each section are complex. Based on geological prospecting data numerical analysis software, stress along characteristic profile were obtained. Taking Shenzhen Nanlong complex interchange project as an example, results show that (1) excavation area Qiaocheng main gradient is large, grade poor, which leads to phenomenon large-area concentration right wall this section. (2) The tunnels in joint construction belong area, influence line stability Baopeng greater than left Baopeng. (3) intersection ramp caused by too distance (4) partitions K3 + 240 multiarch important factor affecting cave.

Evaluation of Effective Parameters on the Underground Tunnel Stability Using BEM
There are various parameters that affect stability and expansion of failure zones in under pressure tunnels. Among the important parameters that affect failure zones around the tunnels are cohesion and internal friction angle of the rock mass. In addition, the cross sectional shape is the considerable point in failure distribution around the tunnels. The stress analysis method is one of the app...
متن کاملNumerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
