Abstract

The invention relates to the technical field of high-speed railway tunnels, in particular to a high-speed railway tunnel reinforcing section stress monitoring device including new tunnel lining, the new tunnel lining is attached to the original tunnel lining. The original tunnel lining comprises an original primary support and an original secondary lining; the novel tunnel lining comprises a steelarch frame and a lining layer, nine groups of uniformly distributed stress monitoring sensors are arranged on the new tunnel lining; each group of stress monitoring sensors comprises two section concrete strain gauges and a section mixed steel bar stress gauge. According to the high-speed railway tunnel reinforcing section state evaluation method, the problems of sensor types and sensor arrangement schemes for monitoring the stress state of a high-speed railway tunnel reinforcing lining are solved, and the high-speed railway tunnel reinforcing section state evaluation method is provided. Themethod plays an important role in monitoring the stress of the tunnel reinforcing section, evaluating the stress state of the tunnel and guaranteeing the operation safety of the high-speed railway tunnel.

Description

technical field [0001] The invention relates to the technical field of high-speed railway tunnels, in particular to a force monitoring device and evaluation method for a reinforced section of a high-speed railway tunnel. Background technique [0002] Affected by construction quality, landslides and trains for a long time, cracks and water seepage will occur inside the high-speed railway tunnel, and in severe cases, concrete will even peel off and fall off, forming blocks, which seriously endanger the safety of high-speed railway operation. In this case, tunnel emergency rescue often adopts re-formwork on the surface of the original tunnel lining, builds a steel arch frame, and pours concrete to form a new lining. In order to grasp the stress state of the tunnel structure in the emergency repair and reinforcement section in time, it is necessary to select a suitable section, apply a suitable stress sensor layout scheme and stress state evaluation method to monitor and evaluat...
