摘要
在立陶宛地区的岩土工程设计中包含了霜深的计算。一年中有三个月的平均气温可能在零度以下，季节性霜冻深度最大可达1.5米以上。分析表明，霜冻在过去200年里一直在减少，尤其是近年来加剧了。本研究的目的是回顾两种不同的测定霜深的方法(LST EN ISO 13793和RSN 156-94)。对主要在道路施工中观测到的干燥和饱和砂土进行了霜深计算。将所得结果与基于道路气象站数据的霜深图进行了比较
Frost Depth Prediction for Seasonal Freezing Area in Lithuania
The calculation of the frost depth is included in the geotechnical design for the Lithuanian region. The average temperature could be below zero for three months a year and maximum seasonal frost depth reaches more than 1.5 m. The analysis has shown that the frost has been declining for the last 200 years, which has intensified particularly in recent years. The purpose of this study is to review two different methods (LST EN ISO 13793 and RSN 156-94) for determining frost depths. The frost depth calculations performed for dry and saturated sandy soils, which are mainly observed in road construction. Obtained results are compared with frost depth map based on road weather stations data
