黄土地区运营公路落水洞路基病害成因分析及处治措施

Cause Analysis and Treatment Measures of Sinkhole Disease on Operating Highway in Loess Area

针对黄土地区运营公路发生落水洞造成的路面沉降和塌落病害,通过工程实例从黄土落水洞的分布特点、成因分析以及针对运营公路在确保通行条件下的处治方案比选等方面,论述了黄土落水洞对路基安全性的评定方法和落水洞的处治办法,并证明了所述运营公路黄土落水洞处治方法的工程实用性。

Focusing on the pavement settlement and the collapse disease caused by the sinkhole on the operating highway in the loess area,in terms of the sinkhole distribution characteristics,cause analysis,and selection and comparison of the treatment schemes ensuring the smooth traffic of operating highways,this paper expounded on the evaluation methods for the subgrade safety of the loess sinkhole and the treatment methods for the sinkhole,and verified the engineering practicability of the proposed treatment methods for the loess sinkhole in operation highways.
