摘　　要：溜砂坡是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。通过对天山公路沿线溜砂坡的调查研究，以K612＋750～K613＋850段特大溜砂坡群为例，阐述该溜砂坡的最基本特性，分析溜砂坡的成灾机理和危害性特点，并对溜砂坡防治措施进行研究。Sand-sliding slope posed a main geological disaster during the highway construction in mountain areas of the west China. Due to ambiguity of formative mechanism of sand-sliding slope, countermeasure employed at p resent could not control the disaster, and some measures even aggravated destruction of slope. By means of investigation and Study of typical sand-- sliding slope along Tianshan Highway, taking the K612＋750-K613-k850 section of especially big sand--sliding slope group as the example, the authors explained the constitutive features of sand--sliding slope, and analyzed its disaster formative mech- anism. Finally, some proper control countermeasures were researched against disaster of sand--sliding slope.
