摘要：
Laboratory tests were conducted to obtain the conduction characteristics of the temperature on the concrete-soil interface and the effect on the contact resistance of the interface in order to analyze the bearing characteristics of static drill rooted pile under the influence of temperature. The tested results show that the contact pressure has no obvious effect on the temperature conduction and the temperature has no obvious effect on the frictional resistance of the concrete-soil interface. A finite element model considering the influence of temperature was established by adopting sequential thermal mechanical coupling method to analyze the bearing characteristics of the static drill pile. The calculation results showed that the influence of the heating and cooling process on the bearing characteristics of the static drill rooted pile was greatly influenced by the pile top load. The variations of the axial force and side friction resistance of precast pile, and the displacement at pile top and pile end, and the vertical stress of cement soil are all related to the pile top load. The bearing characteristics of the static drill rooted pile caused by the heating and cooling have great differences. © 2019, Zhejiang University Press. All right reserved.
