| Abstract: | Qinghai-Tibet Railway faces the problems of high altitude, permafrost, great frequency of freeze-thawing, great temperature difference, low oxygen, unconvenient communication and uneasy maintanance of bridge structure. Obviously, it can improve the outside quality of beam body, increase the efficiency and save the investment by successful application of integral movable outside template in construction of durability simple-supported beam with 32 m prestressed concrete. |
| Keywords: | prefabrication simple-supported beam with prestressed concrete integral template construction application |
