在季節性凍土地區,道路隨季節交替發生凍融循環變化,由此產生的病害主要是凍脹和翻漿等。病害的形成歸根結底屬于熱質遷移問題,而防治凍脹與翻漿的有效措施無不與溫度和濕度有關,搞清冬季凍結過程道路結構體系溫度、濕度及應力的狀況,是正確設計路基路面,防治凍脹和翻漿的先決條件。The month average and the year average water vapor press in chongqing both show that : the water vapor press decreases with the increasing of sea level elevation ; the water vapor press values in north - west and middle hill areas are middle and high ; the water vapor press values in north - east and south - east mountain areas are relatively low. the sea level elevation in north - east and south - east mountain areas of chongqing is higher, especially the north - east mountains are more rugged than the north - west mountains, and the decreasing of water vapor press with the increasing of sea level elevation is more distinct, so the lowest value often appears in the north - east mountains not in the north - west mountains. the seasonal change of water vapor press in chongqing is also distinct : the values of water vapor press are low mostly in winter, and the high values are relatively less ; the values of water vapor press are middle and high mostly in summer, and the low values are relatively less, the values in spring and autumn are between them
