If old water temperature state is not accurately analyzed and calculated, all kinds of damages of subgrade and pavement in the joints between the old places and new places may become possible. This paper analyzes different water temperature states in widening subgrade, as connection between the original and widening subgrades in the frost regions. One may identify the beginning stage, stagnant stage, freezing stage, saturated moisture stage and complete melting stage on the basis of previous studies. The calculation formula for the amount of surplus water is derived with the help of the seepage theory of soil, and some technological measures are proposed to improve the water temperature state and to keep the subgrade in a middle-wet state. The results show that these measures and formulas can help to reduce various kinds of damages of subgrade and pavement in the joints., authors=null, authorsList=null, authorCompany=null,

articleAbstract=冰冻地区在路基加宽时，原有路基的水温状态发生较大变化，如果不改变原有路基的水温状态，在新旧连接部会出现各种路基路面病害。根据加宽路基过程中出现的不同水温状态，划分成开始阶段、积水阶段、冰冻阶段、含水量饱和阶段、完全融冻阶段5个阶段，采用土的基本渗流理论，推导出从旧路基流入加宽路基的过剩水量计算公式，提出改善加宽路基水温状态的措施，为加宽路基的设计提供一定的技术指导。,
