中国土木工程学会建议辽宁省土木建筑学会举办的道路冻害防治学术会议于1964年12月21—26日在辽宁省旅大市召开。参加这次会议的有来自全国25个省、市、自治区的52个单位的代表80余人。会议收到论文共31篇,大会宣读了15篇。这次会议主要围绕以下三个问题进行了讨论。 (一)关于路基水温变化规律方面: 1.地带类型与土基类型划分:大多数代表认为,根据冬季策水来源,可将地带类型区分为受薄膜水影响的干燥地带(第Ⅰ地带)、受悬挂毛细水影响的暂时潮湿地带(第Ⅱ地带),以及受毛细水影响的经常潮湿地带(第Ⅲ地带)。地带类型系以原地面为准。为了和地带类型区别,提出了以路槽底或路肩边缘为准的土基潮湿类型(简称土基湿型)的概念,即以路槽底(或路肩边缘)为准,相应地将土基
China Civil Engineering Society suggested that the Liaoning Provincial Institute of Civil Engineering held a conference on road frost damage prevention and control on December 21, 1964 in Lushan City, Liaoning Province. More than 80 representatives from 52 units from 25 provinces, cities and autonomous regions nationwide attended the conference. The conference received a total of 31 papers, the conference read 15 articles. The meeting mainly discussed the following three issues. (1) As for the rule of variation of subgrade water temperature: 1. Classification of land types and subsoil types: Most representatives think that the types of land belts can be divided into dry land affected by film water (zone I) Moist Zone (Zone II) affected by the suspension of capillary waters and the regular wet zone (Zone III) affected by capillary waters. Strip type is based on the original ground. In order to distinguish it from the strip type, the concept of damp soil type based on the bottom of the groove or the edge of the shoulder is referred to, that is to say, the bottom of the groove (or the edge of the shoulder)
