Standard guide for placement of riprap revetments 拋石護坡堆放標準指南
The temperature properties conditions of a traditional embankment and a ripped - rock embankment were contrasted by laboratory experiments 通過室內試驗研究了在相同溫度邊界條件下普通路基和拋石護坡路基的溫度分布特征,對比分析了兩種路基結構的溫度差異。
Results showed that the temperature distribution of the traditional embankment was asymmetrical ; the asymmetrical status was changed after ripped - rock revetment was installed and the soil under the ripped - rock was cooled obviously ; the ripped - rock revetment could cool embankment and adjust the temperature difference between the north - facing slope and the south - facing slope ; the ripped - rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions 結果表明:普通路基的陰陽坡兩側溫度分布極不對稱;鋪設拋石護坡后,這種狀況得到了很大改善,并且拋石護坡下土體溫度明顯降低;拋石護坡能夠降低路基溫度和調節路基陰陽坡的溫度差異;拋石護坡是多年凍土區防治路基融沉和縱向裂縫病害的一種可行措施。
