| Abstract: | A simulation computation was conducted, by means of a large finite element computation program Ansys 5.6, of the ground temperature field during cast|in|place of a concrete pile at permafrost zone, with consideration of main characteristics of frozen soil along Qinghai|Tibet Railway. The law for distribution of ground temperature field at different ages of pile formation was given, and recommendations were raised for construction of concrete cast|in|place pile at permafrost zone according to the computation result. |
