| 摘 要： | 膨胀土路堤边坡封面是一种保证其正常使用的工程措施.但封面土与膨胀土路堤间的界面又变为整个路堤的薄弱环节.本文综合考虑封面土稳定性以及占地指标和土方量等涉及工程造价的因素,进行相关分析,找出封面土层稳定性良好且工程造价最低的最优填筑形状.

| Abstract: | Use of veneer cover soil on the slope of expansive soil subgrade is a method to prevent early failure of expansive soil subgrade. But the interface between the veneer cover soil and the subgrade is a new weakpoint to whole subgrade. This paper devotes to analyzing synthetically the stability of veneer cover soil and factors relevant to construction cost such as land occupy index and filling amounts, and presenting a optimum filling shape of veneer cover soil. |
