通过对三峡左导墙坝段整个坝体结构及基础从施工期到运行期直至坝体达到稳定温度的全过程进行仿真数值模拟，研究了该坝段温度场及温度应力的分布状况及其历时变化规律。在此基础上，对左导墙坝段温控问题进行了评价，并就存在的问题提出了相应的温控措施。

Through numerical simulation method to simulate the whole process from construction period to operation period and untill the time when the temperature of dam body reaches stability for the dam body structure and its foundation of the leftguide wall dam section of TGP,a study on the temperature field and the temperature stress distribution of the dam section and their duration change regularitiesis performed.On the basis of the result,an assessment on the problem of temperature control for the left guidewall of TGP is made,and the measures of temperature control for the dam section are proposed.
