摘要:
选择合理的开挖进尺是实现隧道安全施工的重要环节,当开挖进尺选择不当时,在软质地层中修建隧道常常会导致掌子面失稳和拱顶塌落。从保证掌子面不失稳和拱顶不塌落的角度,基于谢家杰浅埋隧道围岩压力推导了软岩浅埋隧道开挖进尺的计算公式。并利用该公式计算了天恒山隧道台阶法和CRD法两种工法的开挖进尺,结果表明当采用台阶法施工时,隧道的开挖进尺由掌子面的稳定性控制,而当采用CRD法施工时,隧道的开挖进尺由拱顶的稳定性控制,这说明隧道的开挖进尺不能单独由拱顶稳定性或者掌子面稳定性确定,而是由二者共同确定,从而验证了该公式计算隧道开挖进尺的合理性。
Abstract:
Choosing a reasonable digging length is an important link to realize the safe construction of the tunnel,when the digging length is not selected properly, the construction of the tunnel in the soft stratum formation often leads to the instability of the tunnel face and the collapse of the vault.Based on the theory of the surrounding rock of Xie jiajie shallow tunnel, the formula for calculating the digging length of soft rock tunnel is deduced from the point of view that the surface of the tunnel face is stable and the vault does not collapse.And using this formula to calculate the digging length of bench cut method method and CRD method,the results show that when the bench cut method is adopted, the bench cut method is controlled by the stability of the tunnel face,When the CRD method is used, the digging length is controlled by the stability of the vault, which indicates the digging length can not be determined by the stability of the vault alone or the stability of the tunnel face, but by the two together to determine,Which verifies the formula to calculate the rationality of the digging length
