Measure the bulging behavior of the slab under the road with high precision and utilize it in construction.
In roads and railway tunnels currently in use, there have been cases where the invert is damaged due to the uplift of the ground over a long period, such as from expansive soil, which hinders vehicle passage. To prevent such situations, an invert displacement gauge can be used to measure the amount of uplift in the subgrade during construction, allowing for countermeasures to be implemented as necessary and confirming the convergence of displacement after the measures are taken.
【Benefits of Implementation】
- By using it regularly, you can check for the presence of potential slab bulging behavior, and if such behavior is confirmed, numerical analysis can be conducted using the measurement data to select countermeasures such as invert struts.
- The subsequent uplift can be approximated using an exponential function to predict the residual displacement that the structure will experience after countermeasures are implemented.
- The analysis reproduces the residual displacement to verify the stress on the countermeasures.
- Combined with A measurements in the arch section, it allows for the confirmation of the long-term stability of the entire tunnel cross-section.
