Grouting process for finely controlling deformation of deeply-buried large-section tunnel
The invention relates to a grouting process for finely controlling deformation of a deeply-buried large-section tunnel, which comprises the following construction steps of: (1) acquiring engineering parameters of the deeply-buried large-section tunnel, modeling and simulating, and determining construction parameters of underground excavation construction; (2) a calculation program is operated, and the grouting condition of the underground excavation construction process is determined; (3) preparing grouting slurry; (4) underground excavation construction, grouting, real-time monitoring and adjustment; and (5) after underground excavation construction is completed and slurry is solidified, the grouting effect is detected. The problems that an existing underground excavation advanced reinforcement method cannot be suitable for the working condition of deeply-buried large sections, soil deformation and tunnel deformation are prone to occurring are solved, and the good effect of fine deformation control can be achieved.
本发明涉及一种用于深埋大断面隧道精细控制变形注浆工艺，包括以下施工步骤：(1)采集深埋大断面隧道的工程参数，并建模模拟，确定暗挖施工的施工参数；(2)运行计算程序，确定暗挖施工进程的注浆情况；(3)配制注浆浆料；(4)暗挖施工，注浆，实时监测和调整；(5)待暗挖施工完成且浆料凝固后，对注浆效果进行检测。本发明解决了现有暗挖超前加固方法无法适用于深埋大断面的工况下易发生土体变形和隧道变形等问题，能够实现精细控制变形的良好效果。
