摘　　要：结合兰新铁路第二双线盐渍土路基浸水病害的实际,通过现场勘察揭示了盐渍土溶陷病害的产生原因,提出了堆载预压配合注浆处理的方法处理溶陷盐渍土地基,现场沉降观测数据表明,该方法对于加速溶陷变形沉降完成以及控制工后沉降效果良好,可以在类似工程中推广。Based on the actual situation of the flooding of the second bilateral saline soil subgrade in the Lanxin railway, the causes of the saline soil collapsible were revealed by on-site investigation. The method of preloading and grouting treatment was proposed to treat the collapsible saline soil subgrade. The results show that the method can be popularized in similar projects because the method can treat the collapsible deformation and control post-construction settlement well.
