Measurement and Analysis of Settlement Induced by Rectangular Pipe Jacking in Silt Stratum

The large-scale rectangular pipe jacking technology has attracted more and more attention in the construction of urban underground pipe galleries, especially the problem of prediction and control of the surface settlement. Taking the pipe gallery project of Chengbei Road in Suzhou as an example, the...
