摘　　要：基于静冰压力的计算原理,采用有限单元法,对高寒地区某渡槽内的静冰压力分布特征进行数值模拟分析。结果表明:静冰压力沿程分布不均,静冰压力集中于冰盖15cm以上处,最大静冰压力位于冰盖表层,温升率决定静冰压力的大小,冰层厚度对静冰压力最大值有一定影响。Based on the calculation principle of static ice pressure,the static ice pressure distribution characteristics in an aqueduct in alpine region were analyzed by finite element method,and the results showed that the static ice pressure was unevenly distributed along the course,the static ice pressure was concentrated at more than 15 cm of the ice sheet,the maximum static ice pressure was located on the surface of the ice sheet,the temperature rise rate determined the size of the static ice pressure,and the ice thickness had a certain influence on the maximum static ice pressure.
