英文摘要：

The analytical formulation for ground movement due to tunneling on the basis of stochastic medium theory and relevant back-analysis method are presented.Combined with Shanghai Yangtze river tunnel project,the ground surface movement of test section approach to building areas induced by single tunnel excavation as well as cumulative movement due to two parallel tunnels excavation were accurately predicted using stochastic medium theory.Based on ground movement prediction and evaluation of its influence on surrounding environment,measures for surface movement control（including slurry pressure,synchronous grouting volume and advancing speed） for tunneling in building areas are presented.The study shows that the prediction method developed and measures presented for ground movement control are reasonable and reliable and has some practical value.
