Cangzhou area is one of the most severe areas of land subsidence in the North China Plain, which is a serious threat to major linear projects such as the South-to-North Water Diversion Project and high-speed railroads, and there is an urgent need to carry out a hazardousness assessment for major linear projects. In this paper, the land subsidence hazardousness evaluation was carried out for the northern section of the Beijing- Shanghai high-speed railway in Cangzhou. The evaluation indexes include the slope of land subsidence rate, the severity of land subsidence, the groundwater levels impact and the engineering geological conditions; the evaluation method is hierarchical analysis method and weighted comprehensive evaluation method; the evaluation data period is 2005-2013. The evaluation model was constructed by applying the Spatial Analyst module in ArcGIS, and based on the evaluation results, the land subsidence hazardousness zoning was delineated, and recommendations for the prevention and control of land subsidence were put forward.
