摘要
铁路顶桥工程中遇到砂卵(砾)石层时,因砂卵(砾)石层是一种复杂松散粗碎屑堆积层,因此必须对铁路路基进行加固。介绍采用注浆方式来加固砂卵(砾)石层。工程实践表明,注浆加固技术是对保护铁路路基、保证铁路行车安全的一种有效方法。
Railway jacking bridge engineering passing through sand pebble （gravel） layer, because it is a complex loose coarse fragment accumulation layer, the roadbed must be reinforced. Reinforcing this layer by grouting mode is introduced. Engineering practice shows that the grouting reinforcement technique is an effective method for protecting railway roadbed and ensuring safe running of railway.
