By utilizing the Shanghai Mid-ring Line-Beihong Road underground intersection traffic tunneling project which was constructed by using the pipe-roofing and large section box-culvert jacking trenchless excavation technology
as an engineering background
the authors give a systematic study on the numerical simulation of ground movement in the whole construction process of above-mentioned project by using the ANSYS&FLAC 3-D computer programming respectively.Secondly
by adopting the elastic foundation beam method
lab.-model experiment
and actual test data analogical techniques in situ separately
the authors give a comprehensive study on characteristics of the ground movement variations developed in construction of the large section box jacking with pipe-roofing trenchless techniques.Finally
as adopting the intelligent soft science method
the authors make a so-called “multi-stepped rolling” prediction study by using artificial neural networks(ANN) on surface ground settlement increasing with time around the project.The results have been provided to the design and construction companies for a valuable reference.
