正在编写的《铁路工程地质盐渍土勘测规则》,是继膨胀土、软土勘测规测之后,又一项以特殊土为主题的专用标准。今年4月9～11日,主编单位铁一院在兰州召开了征求意见稿讨论会。出席会议的代表来自勘测设计、施工、运营、科研等部门及单位,共32名。会上,代表们对规则的名称、章节结构及内容广泛发表了意见,并着重讨论了下列问题:盐渍土的定名、分类及计算,对盐渍土地基的原位测试与载荷试验,建立对比关系,关于增加工程地质选线部分内容,新线初测、定测阶段应有不同的工作重点及定量要求等。
The “Railway Engineering Geological Saline Soil Survey Rules” currently under preparation is another special standard with special soil as its theme after the surveying and measuring of expansive soils and soft soil. April 9 ~ 11 this year, the editor in chief of an iron hospital in Lanzhou held a draft discussion seminar. Delegates attending the meeting came from survey and design, construction, operation, research and other departments and units, a total of 32. At the meeting, delegates made extensive comments on the name, chapter structure and content of the rules, and highlighted the following issues: naming, classification and calculation of saline soil; in situ testing and loading test of saline soil foundation; establishing Contrast, on the increase of engineering geological selection part of the line, the new line of the preliminary test, the test phase should have different priorities and quantitative requirements.
