| 摘 要： | 结合青藏铁路沿线多年冻土的主要特点，利用Ansys5.6大型有限元计算程序，对青藏铁路冻土区桥梁混凝土灌注桩基施工过程的地温场进行了模拟计算，分析了高原冻土区桥梁桩基在施工过程中地温场的变化规律，并据此对冻土桩基施工过程中的有关问题进行讨论，所得成果可供相应工程借鉴。

| Abstract: | Based on the characteristics of permafrost in plateau along the Qinghai-Tibet Railway, simulating calculation about the ground temperature during constructing concrete grouting piles is made by finite element program Ansys5.6. The changing rules of the ground temperature field during construction in plateau are analyzed too. According to the results, some problems, which are related to the construction of the pile in permafrost, are discussed. Then, some significant results are presented, which can provide a reference for corresponding engineering. |
