| Abstract: | A new type outer shaft wall structure shape of high strength reinforced concrete precast arch board shaft wall in frozen shaft was put forward,and its mechanics behavior was studied by model test of raw materials. Study indicates that, the new type shaft wall structure shape can work under full loading after assemblage in shaft, and it has great loading capability and good mechanics characteristics. It applied to outer shaft wall supporting in frozen shaft in deep alluvium which deeper than 400 m. |
| Keywords: | high strength reinforced concrete precast arch board shaft wall structure |
