| Abstract: | The main bridge of Liuzhou Sanmenjiang bridge, （ 100 ＋ 160 ＋ 100） m in length, is a 3-span partial cablestayed prestressed concrete box beam bridge with two pylons and double cable planes, Its width is 41 m. This paper puts emphases on construction scheme, construction technology, and construction gist of pier shafts. Temperature surveillance and crack control of mass concrete in construction of pile shafts are expatiated. The engineering practice proved this construction method of pier shafts was reasonable and instructive to similar engineering constructions. |
