针对盾构法隧道工程施工中因地质条件和设备局限性，对超挖和地质突变不能及时掌握，导致地表沉降、涌水涌砂等安全质量事故的发生，提出盾构机盾体径向孔应用这一简易可行的辅助施工方法和应用实例，为盾构隧道工程施工提供一条新的思路。

As for the occurrences of safety quality accidents like ground settlement and gushing water and gushing sand caused by the failure of timely monitoring of over-excavation and geological mutation due to the geological conditions and equipment limitations over the construction of shield tunnel works, this thesis puts forward the application of radial hole on the shield body of a shield machine-a simple and operable supporting construction method, and its application practices, which provides a new way of thinking to the construction of shield tunnel works.
