铁路建设从高铁开始,迈入精细化施工时代早在中国高铁战略确定之初,自主创新的高速铁路建设就被提上了日程。伴随跨越的车速而来的,是对铁路基础设施建设近乎苛刻的要求。高平顺、高稳定作为高速铁路建设的两大关键要求,贯穿于中国高铁建设始终。无砟轨道、路基零沉降、特大桥梁、隧道施工,一系列建设难题都在中国从未有过的精细化土木工 Railway Construction Starting from High-speed Rail and Entering the Era of Fine Construction As early as the time when China’s high-speed railway strategy was finalized, independent innovation of high speed railway construction was put on the agenda. Accompanying the leapfrogging speed is the near-harsh demand for railway infrastructure. As a key requirement for the construction of high-speed railways, high-level smoothness and high stability run through the construction of China’s high-speed railways. Ballastless track, subgrade zero subsidence, large bridges, tunnel construction, a series of construction problems in China have never been refined civil engineering
