全国首届膨胀土科学研讨会于1990年4月19日至23日在成都召开,来自铁路、交通、能源、建筑、水利、电子等14个部门行业、16个省市的专家学者工程技术人员110人参加了会议。会议开会前征集论文90余篇;评选出44篇在开会前编辑出版了“全国首届膨胀土科学研讨会论文集”。在会上作者只谈论文的问题性观点,集中时间提问,并有更多的时间按两个小组讨论共同感兴趣的问题,会议开得活跃,收获大。第一小组讨论膨胀土的工程特性、判别、分类与测试技术。大家认为膨胀土除特殊地貌外,具有膨胀
The first Symposium on Expansive Soil Science was held in Chengdu from April 19 to April 23, 1990. It was attended by 14 sectoral industries including railways, transportation, energy, construction, water conservancy and electronics. Experts and scholars in 16 provinces and cities included 110 People attended the meeting. More than 90 papers were collected before the meeting; 44 papers were selected and edited before the meeting for editing and publishing the Proceedings of the First Symposium on Expansive Soil Science in China. At the meeting, the author only talked about the problem viewpoints of the essay, concentrated time questions, and had more time to discuss the issues of mutual interest in two groups. The meeting was very active and greatly rewarded. Panel I discusses engineering properties, discrimination, classification and testing techniques for expansive soils. We think that in addition to special expansive soil expansive soil, with expansion
