| Abstract: | Tunnels' water seepage problem is quite common in tunnel digging projects,especially at high altitude and low temperature area because of freezing and expansion.Taking Lana mountain tunnel of 318th national highway as reference,this article analyzes and discusses reasons for water seepage in several aspects such as water freezing at seams,cover flashing,blocking water from cranny,drainage and anti-seep beton,etc.and provides relevant preventive methods. |
