岩溶地区的公路路基稳定性及施工设计

Design of Subgrade Stability and Construction

岩溶是一种不良地质现象,岩溶会危害路基,若是溶洞顶板发生坍塌,就引起路基下沉,破坏公路行车安全;并且,若是岩溶地区的地面塌陷,也会降低公路路基的稳定性,对路基施工质量造成破坏。通过研究基于某地公路岩溶区路基施工项目实例,针对岩溶地区公路路基施工设计提出新的决策,构建了岩溶区路基稳定性评价模型,能够优化设计施工决策,确保提升公路路基稳定性。

In practice,karst is a kind of bad geological phenomenon,the harm of karst to roadbed is generally caused by the collapse of karst cave roof and the destruction of karst ground collapse to the stability of roadbed. Through the case study of highway construction project in Karst Subgrade in Karst Region Based on the highway subgrade construction design put forward a new decision,constructed the evaluation model of Karst Subgrade Stability area,can optimize the design and construction of decision-making,ensure that enhance stability of highway roadbed.
