摘要
邻近既有地铁隧道进行桩基施工会对桩基周围岩土体造成一定程度扰动,导致邻近既有地铁隧道发生变形,可能对地铁的安全运营造成不利影响。通过研究桩基施工对邻近既有地铁隧道的影响程度,有针对性采取安全的桩基设计和施工方案,对保障邻近既有地铁隧道的安全有着重要意义。针对桩基施工影响地铁隧道的问题,从基本研究方法、主要影响因素和控制保护措施三个方面的研究进展进行综述,指出尚可继续研究的问题。
Pile foundation construction adjacent to existing subway tunnel may disturb the rock mass around pile foundation to some extent and may cause deformation of the adjacent existing subway tunnel, which may produce adverse influence on safe operation of the subway. This paper studied the influence of pile foundation construction on adjacent existing subway tunnel to propose specific safe pile foundation design and construction scheme, providing great significance for protecting the safety of adjacent existing subway tunnel. Based on the influence of pile foundation construction on subway tunnel, study findings on basic study method, main influencing factors and control and protection measures were introduced to point out issues that could be further studied.
