路基施工中保证路基填筑密实度，通常沙土路基采用水夯；普通路基采用振动碾、羊角碾等重型机具振密夯实。但在缺电、缺水，高气温、大风沙的沙漠气候等恶劣的施工条件下，风沙路基的施工如何保证路基填筑的密实度和施工机械在风沙路基上作业而不陷车的问题，就目前没有合适的经验可借鉴，也没有规范可参考。因此把在包西线神木北至延安北段的铁路工程建设中风沙路基施工所取得的经验和施工技术作一介绍。

In order to ensure the quality filling consistence, water-tamper is generally used on sand soil roadbed and heavy-duty machinery such as suchharsh construction as no electricity, no water, high temperature,heavy wind and sandstorm, there are not suitable experuence and codes to reger to so that the consistence of roadbed filling is ensured and there will be no bog downs when constructing on wind-drift-sand roadbed until now. Fortunately, the author got some experiences from the construction of railroad from northern Shenmu to Yanan part of the Boaotou-Xining railroad line. This paper introduces the construction techniques used in and experiences learned from the construction of this railroad.
