摘要
以甘孜藏区某国道公路高边坡水毁路基工程为依托,通过对水毁路基边坡稳定性分析,验算滑坡推力,并结合工程特点,采用微型钢管桩等工程措施进行了应急抢险和永久加固处治。通过长时间通车运营,验证了微型钢管桩良好的处治效果。
Based on the engineering of a high slope raodbed damaged by water on the national highway in Ganzi Tibetan areas,by analyzing the slope stability of a roadbed damaged by water and cheching the landslide thrust,combined with the characteristics of the project,the emergency treatment and permanent reinforcement treatment are carried out by using micro steel pipe piles and other engineering measures.The good treatment effect of micro steel pipe piles is verified by operation for a long time.
