| Popis: | This paper presents a series of laboratory tests on cemented soil with high water content, and the water content of cemented soil samples were all larger than the liquid limit. A group of model PHC pile-cemented soil interface shear tests were then conducted to investigate the interface frictional capacity. Finally, a group of full-scale tests on PHC pile-cemented soil columns were conducted to study the frictional capacity of cemented soil-soil interface. The test results show that: the cohesion of cemented soil with high water content had a linear relationship with the unconfined compressive strength; the cemented soil strength had a large effect on the frictional capacity of PHC pile-cemented soil interface, and the peak skin friction of PHC pile-cemented soil interface increased linearly with the increasing cemented soil strength; the frictional capacity of cemented soil-soil interface was better than the frictional capacity of conventional pile-soil interface. |
