摘要
对不同起始含水率、掺入石灰率以及击实功试验条件下的大试件膨胀率进行了分析,得出了膨胀率与起始含水率为对数关系曲线,膨胀率与掺入石灰率、击实功为不同的幂函数关系曲线,研究结果为膨胀土地基的设计及膨胀土地基处理等膨胀土问题提供了重要的依据。
By studying the expansion ratio of different beginning water content,doped lime content and hammering workdried,the result showing that the variational rule of swelling ratio and the beginning water content fitted curve is the logarithm relation,the variational rule of swelling ratio and doped lime content,hammering workdried fitted curve are the difference power function relation. The study results have provided the important basis for the design and treatment technique to the existing expansive soil foundation.
