楚大高速公路边坡治理

Slope Treatment of Chuda Highway

楚雄至大理高速公路从投入运营至今已17年有余,期间路面、边坡等设施已经过多次维修。路基边坡在多次极端气候情况下发生坍塌、失稳,给公路安全运营带来隐患,需对该路段边坡进行处理。本文针对楚大K68＋300~K68＋510路段应用FLAC3D进行模拟分析并提出治理意见。

Chuxiong to Dali Expressway has been more than 17 years from the input operation, and during this period, the road, slope and other facilities have been repaired several times. Subgrade slope in the case of multiple extreme climate occured collapse and instability, which has brougth hidden dangers to the safety of the road, so it is necessary to deal with the slope of the road. In this paper, it uses FLAC3D to take a simulation analysis on Chuda K68＋300 ~ K68＋510 section and puts forward management advices.
