摘要
针对轨道交通中整体道床剥离脱空等问题,从地质条件、设计、施工、运营维保等方面综合分析整体道床剥离的原因,根据地质条件及道床剥离程度将整体道床剥离状态分成3类,结合道床剥离的特点对于不同类别的道床剥离状态有针对性的提出先检测再制定整治方案、后治理验证的成套控制技术,以解决道床剥离反复的问题,降低养护费用,为整体道床类似病害的整治提供借鉴。
Aiming at the separate problems of monolithic track-bed in rail transit, separate causes of monolithic track-bed were analyzed from aspects of geological conditions, design, construction, maintenance, etc. Separate state of monolithic track-bed was divided into three categories according to geological conditions and separating degree. Combined with characteristics of monolithic track-bed, remedial technology that was targeted at different categories of monolithic track-bed state was put forward. The remedial technology could solve the separate problem of monolithic track-bed and reduce maintenance cost, which can be used to similar projects.
