Abstract:

A tunnel on Ning-Huai highway is a shallowburied soft ground tunnel with large span. Dynamic feedback design and informationaided construction are executed for the tunnel. By means of TSP203 advance geology forecasting system and monitoring and measurement, the construction information is collected, analyzed and fed back and good effects are achieved in respect of ensuring the construction safety, optimizing the design and providing guidance for the tunnel construction. The paper can provide basis and reference for similar works in the future.
