Embodiment 1
[0057] High Liquid Limit Red Clay of Hainan Haitun Expressway
[0058] The subgrade construction test of the new method was carried out in the K6+220~K6+420 section of the Haikou-Tunchang Expressway in Hainan. The disturbed soil samples of high liquid limit red clay were collected on site, and the basic physical property indexes and engineering property tests were carried out. The indoor test results show that: the natural moisture content of the high liquid limit red clay of Haitun Expressway is 31.8%, which is greater than its plastic limit of 30%, and its liquid limit is 34%, so it is judged that the soil is an over-humid high liquid limit soil; the natural dry density is 1.46g / cm 3 . The compaction controlled moisture content obtained by the compaction control method aiming at the maximum bearing capacity is 22.5%, and the dry density corresponding to the compaction curve is 1.74g / cm 3 .
[0059] The average annual temperature in Hainan is high, the temperature differe...
Embodiment 2
[0075] Guangdong Granite Residual Soil Example
[0076] The subgrade construction test of the new method was carried out in the K110+000~K110+200 section of Guangdong Guangfo-Zhaozhou Expressway. Disturbed soil samples of granite residual soil were collected on site, and basic physical property indexes and engineering property tests were carried out. The indoor test results show that the natural moisture content of the granite residual soil on the Guangzhou-Foshan-Zhaozhou Expressway is 26%, which is greater than its plastic limit of 25%, and its liquid limit is 32%. 1.44g / cm 3 . The compaction controlled moisture content obtained by the compaction control method aiming at the maximum bearing capacity is 18.3%, and the dry density corresponding to the compaction curve is 1.65g / cm 3 .
[0077] Guangdong has abundant precipitation, with an average annual precipitation of 1,300 to 2,500 millimeters, and an average of 1,777 millimeters in the whole province. The annual distri...
