the two-dimensional phase change temperature field of petroleum pipelines in seasonally frozen ground regions under severe climate conditions is studied.
研究了季节冻土地区集(输)油管线基础土体在冬季冻结期间的相变温度场的奇异摄动解法。
water migration and variation in subgrade soils is the most active and live factor to the road frost damage in seasonally frozen ground regions.
在季节冻土区,路基水分迁移变化是道路冻害最积极活跃的因素。
it is shown from the results that seasonally frozen ground evidently influences site dynamical characteristics and seismic security of tank.
结果表明:季节性冻土层的存在明显地影响着场地动力特性,进而影响储罐的抗震安全性。
