隧道能够安全长时间的使用是对人自身安全的一种保障,只有将隧道水的排放和预防的措施做好才能够实现隧道的安全使用。所以,在隧道的设计当中,水的预防和排放措施的设计才是重中之重的问题。合理的设计出防排水设计是隧道设计中的重要问题,隧道在渗透漏水的长期作用下,能造成隧道侵蚀破坏,尤其在严寒区域,寒冷天气的入侵使得冻融循环,造成了在衬砌的局部胀裂并受到了严重的破坏;而且使得因衬砌和围岩之间因冻胀而造成墙体出现破坏并出现了严重的墙体形变。
The safe and long-term use of tunnels is a guarantee to people’s own safety. Only when tunnel water discharge and prevention measures are well done can tunnels be safely used. Therefore, in the design of tunnels, the design of water prevention and emission measures is the most important issue. Rational design of drainage and drainage design is an important issue in tunnel design. Under the long-term effect of seepage and water leakage, the tunnel can cause erosion and damage to the tunnel. Especially in the cold area, the invasion of cold weather makes the freeze-thaw cycle, Cracked and severely damaged; but also caused by the wall between the lining and surrounding rock due to frost heaving damage and the emergence of a serious wall deformation.
