| 摘 要： | 结合成都地铁某区间盾构隧道施工情况,根据实测的地表沉降数据,分析了盾构推进时对地表的横向沉降影响。通过实测数据得出Peck法计算参数,用实测值来验证Peck曲线预测沉降的吻合程度。分析表明:当沉降槽宽度系数k在0.13～0.31之间时,可以较好地反映出横向沉降规律。

| Abstract: | The affection of ground settlement caused by shield advancement is analyzed according to the measured surface settlement data from a section of metro construction in Chengdu City.The Peck method parameters are calculated through the measured data,and the Peck curve is verified by the consistent extent of the settlement prediction together with the measured values.This analysis shows that the rules of transverse ground settlement can be preferably reflected when the value of k is between 0.13~0.31,and the re... |
