摘要:
分散性土一直为岩土工程中的重要研究问题之一,在工程上容易引起管涌、路基失稳等破坏.目前判别土的分散性试验主要有双比重计试验、针孔试验、碎块试验、孔隙水可溶性阳离子试验和交换性钠离子百分比试验等5种,但判别标准和结果各不相同,无法明确判定土的分散性.有学者提出通过赋予各试验方法所得结果不同权重的方法进行综合判别,该方法得到了广泛应用和推广.作为公认的多种鉴别方法中最为直接可靠的针孔试验,由其得出的结果比较有说服力.因此,需要进行一系列的针孔试验,判断陕西泾阳某滑坡土的分散性,以期望提供治理滑坡灾害方面的建议.
Abstract:
Dispersive soil has always been one of the significant research problems, which is easy to cause piping and roadbed instability and other damage in engineering. At present, there are five kinds of dispersion tests for discriminating soil, such as double hydrometer test, pinhole test, crumb test, pore water salts test, and exchangeable sodium percent test; however, the dispersity of soil cannot be clearly determined due to the different criteria and results. Some scholars have proposed a method of comprehensive discrimination by assigning different weights to the results obtained by each test method, which has been widely used and promoted. The pinhole test, as the most direct and reliable test among the recognized identification methods, is quite convincing. Therefore, it is necessary to carry out a series of pinhole tests to determine the dispersion of a landslide soil in Jingyang, Shaanxi Province, in order to provide suggestions for the treatment of landslide disasters.
