摘要
为掌握我国高速铁路路基服役状态、养护维修技术与管理现状,开展了系统的调研与分析。结果表明:高速铁路路基整体运营情况良好,发生过病害的长度占路基总长的6. 51%;病害类型主要有沉降、排水不良、封闭层破损、翻浆冒泥,个别地域存在冻害、上拱、危岩等问题。在高速铁路路基检修过程中,存在人员配备不足、检查条件和机具有限、缺少有效的检查及维护手段等问题。总结了路基结构、边坡以及防排水系统相关的主要病害的现状、成因以及整治措施。
In order to grasp the service state,maintenance technique and management state of high speed railway subgrade in China,systematic investigation and analysis were carried out.The results show that the overall operation of the subgrade is in good condition,and the length of the subgrade that has been damaged accounts for 6. 51% of the total length of the subgrade.The types of diseases mainly include subgrade settlement,impeded drainage,sealing layer broken,mud pumping.Frost heaving,subgrade heaving and dangerous rock are also happened in some areas.In the process of high speed railway subgrade maintenance,there are some problems of insuff icient staff ing,limited inspection conditions and machines,and lack of effective inspection and maintenance measures. This paper summarizes the current situation,causes and treatment measures of the main diseases related to subgrade structure,slope and w aterproof and drainage system.
