摘　　要：依托于北京轨交8号线某区间盾构隧道工程,基于Peck理论和预测建筑物沉降的刚度修正法,通过对现场变形监测数据的分析,研究北京旧城地区盾构施工引起的地表和古旧平房群沉降规律,并提出了适用于盾构施工下穿古旧平房群的沉降预测方法。Depending on an interval tunnel of Beijing Rail Transit Line 8,based on the Peck theory and stiffness modifying method for building settlement prediction,the on-site deformation monitoring data is analyzed to study the settlement rule of ground surface and old one-storey houses which is caused by shield tunnelling in Beijing old city area,and construction settlement prediction method is proposed.
