公路施工中消除土方路基常见病害的具体措施

Measures to Eliminate the Common Diseases of Earthwork Subgrade in highway Construction

分析了公路土方路基常见质量病害的成因,其次,从重视前期工作、控制软弱地基工后不均匀沉降、合理处理水位较高的零填或低填方地段、合理处理湿陷性黄土地段或膨胀土地段、采用加固技术等方面深入探讨了土方路基常见质量病害防治办法和控制措施,以便延长公路路面使用寿命。

This paper first analyzes the causes of highway earthwork subgrade common quality diseases. Secondly, from paying attention to the preparatory work, control weak foundation uneven settlement, rational treatment of water level is higher than that of the zero filling or low fill area, reasonable treatment of collapsible loess area or swelling soil area, the strengthening technology deeply discussed the roadbed earthwork common quality measures for the prevention and control of diseases and control measures in order to extend the highway pavement service life.
