| 摘 要： | 根据软弱围岩隧道变形的基本规律，系统总结了国内外，尤其是日本控制隧道开挖后变形的基本对策，包括：1）控制先行位移的技术--超前支护；2）控制掌子面挤出位移的技术--掌子面补强；3）控制脚部下沉的技术--脚部补强；4）加强初期支护的对策。

| Abstract: | Deformation controlling technologies for tunnels in China and abroad, especially in Japan, are systematically summarized on basis of the basic deformation rules of tunnels with soft surrounding rock. The technologies include advance support technology (advance displacement controlling technology), tunnel face reinforcement technology (tunnel face extrusion displacement controlling technology), arch feet reinforcement technology (arch feet settlement controlling technology) and countermeasures to strengthen the primary reinforcement. |

| Keywords: | soft surrounding rock tunnel deformation deformation control advance displacement extrusion displacement allowable deformation value advance support tunnel face reinforcement arch feet reinforcement primary support |
