| 9. | The result indicates that under the condition of temperature sudden drop , the temperature of face slab ' s surface and centre will fall consecutively along with the temperature sudden drop , and the face slab ' s surface temperature drop - cut range will reach maximum ; under this condition , the tensile stress appears in the face slab ' s surface and centre , the maximum principal stress in the face slab ' s surface is larger titan that in the face slab ' s center ; the maximum principal stress in the face slab ' s surface and centre both occurs in the position that the elevation equals approximately to half of the dam ' s height
结果表明，在气温骤降条件下，面板表面及中心的温度将随气温骤降的发生而持续降低，其中面板表面温度降幅最大；此时面板表面和中心均出现拉应力，面板表面的最大主应力大于面板中心的最大主应力；面板表面和中心的最大主应力均发生在高程约为坝高一半的位置。 |
