摘　　要：沙漠与戈壁常被统称为沙漠,但二者成因不同,对公路的影响也显著不同。在沙漠中公路的路基高度已有研究成果的基础上,进一步探讨影响戈壁地区公路路基填筑高度的控制因素,提出在合理填土高度的确定原则下,用工程经济对比法确定路基的合理填土高度。Typically, desert and gob1 are aenommatcu a~ , geneses thus have significantly different effects on highway. Based on the achievements in respect of the research on height of highway subgrade in desert, the further study was conducted in connection with the factors affecting filling height for highway subgrade in gobi regions, and then the proper filling height was confirmed under the related principles by the contrast method of engineering economics.
