| 摘 要： | 溜砂坡足我国西部山区公路的主要地质灾害之一。由于对溜砂坡的形成发展机理认识不足，目前采用的治理措施不能很好地解决溜砂灾害，有些工程措施反而会加大灾害程度。通过对川藏公路沿线溜砂坡的调查研究，阐述了溜砂坡的最基本特性是其生长性，分析了溜砂坡的成灾机理和危害性特点，有针对性地提出了符合西部地区经济条件的溜砂坡防治措施。

| Abstract: | Sand-sliding slope posed a main geological disaster in mountain area highway construction in west China. Due to ambiguity of formative mechanism of sand-sliding slope, countermeasure employed at present could not control the disaster, and some measures even aggravate destruction of slope. By means of investigation and study of typical sand-sliding slope along Sichuan-Tibet Highway, explained growth with time was constitutive feature of sandsliding slope, and analyzed its disaster formative mechanism. Finally, based on economic and geological condition of west China, some proper control countermeasures were suggested against disaster of sand-sliding slope. |
