摘要
为解决季节冻土区公路桥涵地基土冻胀性判定条件问题,黑龙江省交通科学研究所作了大量试验研究工作。本文根据粘性土、细砂的原形冻胀试验及对实测资料的数学加工和吸取有关冻土分类之经验,提出公路桥涵地基土冻胀性五级分类及其依据。
To establish criteria for the subsoil frost heave susceptibility of highway bridge in seasonal frost region, extensive experimental studies have been undertaken by the Heilongjiang Institute of Highway and Transportation Research, In this paper, a 5-grade classification and its criteria for the subsoil frost heave of highway bridge are set forth on the basis of in-situ frost heave experiments on both clay and sand, mathematical treatment of the data and reference on frozen soil classification as well.
