Construction Technology and Monitoring Analysis of Strata Strengthening of Digging Tunnel Undercrossing the Overpass
The complex construction conditions of subway stations undercrossing overpasses involve the coordination of underground structure construction and ground traffic structure.Efficient and reliable stratum reinforcement technologies and key index monitoring are important means to ensure smooth construction.Taking the underground excavation channel of Jinan Metro Line 4 undercrossing an overpass as an example,the main risks of the project are analyzed,and the advanced deep hole grouting stratum reinforcement technology is proposed.The monitoring data of surface settlement,channel structure deformation and overpass settlement during the construction process are analyzed,and the corresponding measures are put forward.
