Now, the scholars of internal and overseas pay close attention to the mechanics function of sfrc, such as in the references [ 3, 13, 14, 16, 23, 27, 28, 29 ], and so on. however, in the practice pavement engineering project, the sfrc is given not only the effect of vehicle and shock load, but also the effect of the temperature changes and sun radiation. therefore, the temperature and load stress are the main factor of the damage of the rigid pavement structure. because of the existent of the temperature stress, the sfrc pavement structure may be destroyed by the expand of crack. therefore, the research and analysis of the temperature load and stress of sfrc pavement structure are important to control the crack of sfrc pavement structure
目前，國內外學者對鋼纖維混凝土的研究著重於鋼纖維混凝土的力學性能，如文獻[ 3 ， 13 ， 14 ， 16 ， 23 ， 27 ， 28 ， 29 ]等。而鋼纖維混凝土在實際路面工程的應用中，不僅要受到路面車輛移動載荷和沖擊載荷的作用，還要承受路表的溫度變化及日輻射的作用，所以溫度應力與車輛荷載應力同樣都是剛性路面產生破壞的主要因素。由於溫度應力的存在，會引起鋼纖維混凝土路面板結構產生裂紋。 -
