Abstract

The invention provides a tunnel arch crown settlement and peripheral convergence monitoring method. The tunnel arch crown settlement and peripheral convergence monitoring method comprises installing a rope free of elastic deformation, wherein one end of the rope is fixed on an arch foot arranged at one end of every tunnel section, the other end of the rope is tied on an electric spring scale after calibration, the spring scale is located on an arch foot arranged at the other end of every tunnel section, and the middle portion of rope penetrates a tunnel circular arch; pre-applying the initial force when the monitoring is started to enable an initial reading to be displayed on the electric spring scale, pulling the rope to enable the initial reading on the spring scale to tend to be stable and recording; repeating the above steps and deploying the same way of monitoring on the plurality of sections; performing continuous observation on readings of the electric spring scale during tunnel construction, suspending the construction if the readings are changed, performing repeated observation on the tunnel sections through a full-drilling machine or a three-dimensional laser scanner and performing real-time treatment when problems are found. A tunnel arch crown settlement and peripheral convergence monitoring device is simple, free of model prediction, small in calculation amount and free of technical difficulties and workers can timely find dangerous situations conveniently.

Description

technical field [0001] The invention belongs to the field of monitoring and measuring, in particular to a method for monitoring tunnel vault settlement and peripheral convergence. Background technique [0002] Due to the characteristics of concealment, uncertainty and variability, the construction of underground projects such as tunnels is difficult to construct, and it is easy to cause various engineering quality accidents, which seriously affects the construction progress and quality of the project. Construction monitoring and measurement The purpose is to monitor and grasp the stress and strain of the engineering structure in a timely manner, carry out information processing, guide the construction of the project, ensure construction safety and long-term stability of the structure, verify the effect of the support structure, accumulate measurement data, and provide a basis for information design and construction . [0003] In tunnel construction, the most important task ...
