摘　　要：根据模拟所得出的结果,提出施工建议:工作井开挖需对井底部土体的隆起现象加以重视,做好工作井的位移监测工作,防止井位偏移影响施工;避免顶管顶进时地表沉降或隆起过大,影响周围建筑物,在发生地表沉降或隆起处采取土体加固等预防措施;针对顶管工作井的支护方法及要求,行业应及时推出相应的规范,为顶管逆作井的开挖、支护以及工作提供相应的依据。Based on the simulation results,construction suggestions are proposed:during the excavation of the working well,attention should be paid to the uplift phenomenon of the soil at the bottom of the well,and displacement monitoring of the working well should be carried out to prevent the deviation of the well position from affecting the construction.To avoid excessive surface settlement or uplift during pipe jacking,which may affect surrounding buildings,preventive measures such as soil reinforcement should be taken at locations where surface settlement or uplift occurs.The industry should promptly introduce corresponding standards for the support methods and requirements of top pipe working wells,providing corresponding basis for the excavation,support,and work of top pipe reverse working wells.
