论公路工程中膨胀土路基的施工处理方法

Construction Method of Expansive Soil Subgrade in Highway Engineering

公路工程中膨胀土路基比较常见。公路路基施工时,为了保证膨胀土路基的稳定性和安全性,施工之前必须对膨胀土的工程特性进行细致的试验分析,进而确定出膨胀土的亲水强弱性,然后选择正确的方法来处理膨胀土路基。

Expansive soil subgrade is common in highway engineering. For ensuring the stability and safety of expansive soil subgrade, the engineering characteristics of expansive soil must be analyzed in detail by tests before the construction of subgrade. Furthermore, the degree of hydrophilicity of expansive soil is fixed on. Then a correct method is chooen to treat with the expansive soil subgrade.
