摘要
在对现场实测数据进行统计分析的基础上，建立了模拟台阶法施工的有限元解析模式，并用此方法，评价了台阶法、注浆、喷层、锚杆等主要工程措施对控制隧道围岩变形的效果，为新奥法施工的浅埋隧道控制地表下沉提供了理论依据。
On the basis of data measured at the site of tunnel, the finite element method simulating the details of bench cut construction is established. The main engineering measures (bench cut method, grouting, shotcrete, rock bolt)that control the deformation in the surrounding rock of the tunnel are discussed. The theory of controlling tunnel ground surface settlement in NATM construction is given.
