Abstract:

The limitations of expansion capacity calculating method in current existing standards are analyzed. Based on the testing results of load expansion ratio of expansive soils in Huai’an section of Ning-Huai expressway, the relationships between the load expansion ratio and initial moisture ratio, the upper load as well as degree of compaction are analyzed. The relationships between the load expansion ratio and the initial moisture ratio, the upper load and the degree of compaction of the compacted expansive soils are proposed, and have been used to calculate the possible expansive deformation if the embankment of Ning-Huai expressway is filled with the expansive soils directly. The influence of initial moisture ratio on expansion capacity is also analyzed.

Key words: compacted expansive soil, expansion capacity calculation, Ning-Huai expressway, load expansion ratio, initial moisture ratio
