| 英文摘要 | Vertical uplift static loading tests of single model pile were conducted in the in-lab calcareous sand and quartz sand by emulating practical condition of full-size piles in site. The settlement, lateral deflection, axial force, and friction distribution of the pile are analyzed for each physical test. The pile behaviors in calcareous sand and quartz sand are compared. From the test results, it can be found that the pile top displacement of uplift pile in calcareous sand can be divided into two stages: the pile-sand synchronous stage and pile-sand asynchronous (relative displacement) stage. Data from uplift tests show that the heave of calcareous sand around pile top is very small, which is resulted from the mutually restraint of surface particle. The mutual restriction of surface particle leads to bottleneck effect and strengthens ultimate side friction of upper pile segment. In addition, the shear dilatancy and particle breakage of calcareous sand lead to the upper harden and the lower soften of side friction, respectively. Cases of calcareous sand and quartz sand show different responses to pile forming methods, which due to the sands' different characteristics of particle breakage when compressed as well as plastic deformation under loading-unloading conditions. |
