摘要
新疆阜康地区在冬季土体冻融环境影响下,渠道衬砌易开裂、坍塌,研究冬季渠道衬砌的冻胀破坏机理十分必要。采用高分子合成材料EPS(发泡聚苯乙烯)颗粒轻质土垫层作为渠道的保温措施,分析不同掺量EPS颗粒轻质土垫层情况下土体的温度场及位移场。
The tunnel lining is easy to crack and collapse under the influence of soil freezing and thawing environment in Fukang area of Xinjiang in winter,so it is necessary to study the frost heave failure mechanism of the tunnel lining in winter.It is determined that the polymer composite material EPS(expanded polystyrene)particle lightweight soil cushion is adopted as the insulation measure of the channel.The temperature field and displacement field of soil under different EPS particle lightweight soil cushion are analyzed.
