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.
