【摘要】：欧洲规范体系(即EN标准),按参加国所承担的共同义务将赋予某成员国的有关国家标准以合法地位,或撤销与之相对立的某一国家的有关标准,该文涉及到的欧洲标准均为法国标准。欧洲标准根据填料的性质、力学性能和状态将路基填料分为若干详细类别,针对不同类别的填料,采用不同的处理措施(如洒水、晾晒或掺灰等)、选择相应的填筑方法(选择适当的碾压设备、碾压遍数等),并控制安全的路堤高度(对于细粒土,填筑高度过高会影响路堤边坡的稳定性),以此来优化路基路面结构设计,从而降低工程造价,确保工程安全。
[Abstract]:The European system of norms (i.e. en standards), in accordance with the common obligations assumed by the participating States, will give legal status to the relevant national standards of a member State or revoke the relevant standards of a State in opposition to them, The European standards involved in this paper are all French standards. According to the properties, mechanical properties and state of the fillers, the European standard divides subgrade fillers into several detailed categories, and adopts different treatment measures (such as sprinkling water) for different types of fillers. To dry or mix ash, etc., select appropriate filling methods (select appropriate compaction equipment, number of compaction times, etc.), and control safe embankment height (for fine grained soil, etc.) Too high filling height will affect the stability of embankment slope, so as to optimize the structural design of subgrade and pavement, thus reduce the engineering cost and ensure the safety of the project.
