青藏铁路格拉段沿线地质复杂,线路穿越多年冻土区,高寒缺氧、生态脆弱。电力管桩基础施工难度大,时间紧,通过对青藏铁路D2标段工程施工,总结高原多年冻土区电力管桩施工技术。
The geology along the Gela section of the Qinghai-Tibet Railway is complex. The route crosses the permafrost zone with high altitude and lack of oxygen and is ecologically fragile. Power pipe pile foundation construction is difficult and time is tight. Through the construction of D2 section of Qinghai-Tibet Railway, the construction technology of power pipe pile in permafrost region is summarized.
