摘　　要：通过对黄土地区黄土陷穴形成和扩展机理的认识,指出湿陷性黄土的失陷性是产生陷穴的基因,水的潜蚀作用是产生陷穴的诱因和动力。分析了黄土陷穴对陕京输气管道的影响及危害,提出了对黄土陷穴的预防及处理措施。Shaanxi-Beijing Gas Transmission Pipeline, with 660 mm in diameter and 847. 8 km in total length, was put into operation in September of 1997. The several kilometers of the pipeline was located at the Loess Plateau in the Northwest of China. The serious loess sinking problem produced by the unique geological conditions ,which influenced the safety operation of the pipeline. The geological analysis on the harm of loess sinking to the pipeline is performed, including the formation and development mechanism of the loess sinking. According to the analytical results,some protection measures are put forward.
