摘要
以浦南高速公路C2合同段为工程背景,按照不弃土、不改良原则,通过室内、室外试验,分析了土的强度、干密度、饱和度、膨胀量与含水量、击实功的关系,据此得到了高液限粘土最佳含水量范围,提出了高液限粘土用于路基填筑的控制标准,即可用含水量及其对应的干密度、压实度和饱和度要求值,为本工程施工提供了依据。本文的研究对促进高液限粘土在路基填筑中的应用具有重要参考价值。
With the section of Contract C2 of the Pu-Nan Expressway as a practical example,on the principle of no spoil and no modification and through indoor and outdoor tests, the relations among the strength, dry density, saturation, expansion volume and water content of the soil and the compaction work are analyzed in the paper, upon the basis of which the optimum water content of high liquid limit clay is obtained, with the control standard for it in filling the roadbed put forward, namely, the val- ues of the feasible water content and the corresponding dry density, the degree of compaction and saturation of the soil, which provide technical grounds for the construction of the project. The study dealt with in the paper may serve as an important refer- ence for the promotion of the application of high liquid limit clay to filling the roadbed.
