| 摘 要： | 云南大保高速公路K399滑坡，于1999年4月16日初次滑动，以后又经过多次滑动和整治，但滑坡仍不稳定。在总结和回顾该滑坡发展变化的基础上，根据大量的地质资料，分析了滑坡的地质条件、成因和力学机制。确定其力学性质为牵引-推移式大型碎石土-岩质滑坡。对涔坡稳定性作了定性、定量分析和评价。根据该滑坡活动特点和滑坡特征，经综合分析研究和计算后，采取以桩板墙、预应力锚索抗滑桩为主体工程，辅以锚固、护坡和排水的综合治理措施，既根治了滑坡，又获得了良好的治理效果，为大保高速公路的全线贯通争取了时间。

| Abstract: | The K399 landslide on Dali-Baoshan motorway, Yunnan, had silded for the first time on April 16,1999. After that andslide slided and was treated many times, but this landslide wasn't stable yet. In this paper, based on both the development of this landslide and a great deal of geological data, geological condition, and mechanism are analysed. The landslide's mechanics nature is a tow-propeled type large gravel-rockmass sildeslide. The landslide stability is evaluated on quantitative analysis. Comprehensive control measures, pile-board-wall and anti-slide pile with pre-stressed anchor wire associated with anchor, slope protection and water drainage, were used. This comprehensive treatment controlled the landslide, not only gained good effects, but get it early run through for Dali-Baoshan motorway. |
