以朔黄铁路神池南站既有铁路路基病害为背景，对现场路基病害进行调查及观测，有选择性地对现场15个点进行了取样试验。通过现场钻测、室内常规试验，就填料的类型、土体的含水量、站场排水等影响因素进行了深入的分析；采用轻型动力触探技术对路基承载力进行了检测，确定了路基病害的范围与深度及路基病害产生的原因，提出了整修建议。

Taking the subgrade detects found on the existing line at Shenchi South station of Shuohuang railway as a background, an investigation and observation are carried out on-site over the subgrade defects. 15 points on-site were selectively sampling tested. Through on- site drilling and measurements and indoor routine tests, filler type, soil water-content, station drainage and other affecting factors were tinder in- depth analysis; light-duty dynamic penetration technology for detection of subgrade bearing capacity were tested to determine subgrade defects in terms of the range scope and depth, the causes of subgrade detects and some treatment proposals are put forward.
