Abstract: At present, the finite element method is adopted to simulate the interaction between retaining structure and soil during the pit excavation. Based on it, the authors put forward a method which couples the temperature field to the stress field to analyze the pit strut temperature effect. Combining case history, it is simulated by adopting modified Cam-clay model and considering different excavation processes. And it analyzes the strut temperature stress effect caused by different construction stages. Then it is pointed out that the strut temperature stress should be designed according to the worst cases caused by all kinds of work conditions. It comes conclusions that the effects of the temperature should be considered as a case when it changes greatly.

Key words: pit support, axial force of strut, temperature stress, finite elements, modified Cam-clay model
