太中银铁路某高边坡鼓胀病害整治技术研究

Study on Treatment Technology of Expansion Defect in High Slope on Taiyuan-Zhongwei (Yinchuan) Railway

路堑边坡通常采用锚索(杆)框架梁加固,这种加固方式对边坡裂隙的发展能起到控制作用,可以有效约束坡体的变形。针对太中银铁路某四级边坡鼓胀病害展开现场调查,综合分析了其发生鼓胀的原因。通过边坡不平衡推力法计算分析,提出了使用锚索(杆)框架梁加固边坡的方案,明确了纵横梁以及锚杆的尺寸、连接、锚固等关键参数。锚索(杆)框架梁方案具有施工便利且纵横梁体系稳定可靠的优点,能确保边坡的长期稳定,并满足铁路安全运营的要求。

The anchor cable（rod） frame beams are usually used for reinforcing cutting slopes. This Method can effectively control the expansion of slope cracks and constrain slope deformation.For treating the expansion defect of a four level slope on Taiyuan-Zhongwei（Yinchuan） Railway, the defect causes were comprehensive analyzed through field survey.The strengthening scheme using frame beam with anchor cable（rod） was put forward based on the calculation and analysis by imbalance thrust method.The key parameters such as dimension,connection and anchorage of the vertical and horizontal beam and the anchor rod were determined. The construction of the anchor cable（rod） frame beam is convenient and the vertical and horizontal beam system is stable and reliable,ensuring long-term stability of the slope and meeting the requirements of slope safety.
