客运专线线下工程的“工后零沉降”建设理念探索

Under after the passenger transportation special line line the project ＂the labor the zero subsidence＂ the construction idea explores

铁路客运专线有碴轨道对线路的平顺性提出了严格的要求，在秦沈客运专线施工中首次提出了“工后零沉降”建设理念，客运专线无碴轨道对线下工程的沉降所引起的轨道永久变形做出更加严格的限制，设计和施工中以“工后零沉降”为追求目标，将线下工程的工后沉降控制到最少值。

content summary： The railway transportation special line had is cut by broken glass the track to propose to the line smoothness the strict request, passenger transportation special line construction proposed for the first time after Qin in the Shen ＂the labor the zero subsidence＂ the construction idea, the passenger transportation special line not was cut by broken glass the track the orbital permanent deformation which the project subsidence caused to the line under to make a stricter limit, in the design and the construction after ＂the labor the zero subsidence＂ as the pursue goal, after the project labor subsided the line under controls the least values.
