摘要
研究了注浆法在黄土地区公路路基洞穴处理中的加固机理及技术指标。黄土地区公路中的洞穴对公路的安全运营常造成严重危害,同时对于这类洞穴的处理尚缺乏有效的方法。在大量调查和参考前人研究成果的基础上,将注浆法用于路基中洞穴的处理,提出了注浆法加固的主要设计参数,通过对施工现场黄土洞穴注浆处理效果分析,认为该方法具有良好的处理效果。
The principle and index that roadbase cave in collapsing loess areas treated by grouting are studied. There are so much harmness in highway caused by cave in roadbase in collapsing loess areas,however,there are still lack of an excellent way to make up of it.Based on lots of survy and futher study,the parameter of design is suggested.After analysis the data on spot,it is concluded that grouting is an effective method.
