西安市轨道交通Ⅱ号线B标岩土工程特征

The Geotechnical Engineering Characteristics of Lot B of the Urban Mass Transit Line 2

地铁设计需要多种岩土参数,这些参数可通过室内试验及现场原位测试获得。文章以西安市城市快速轨道交通Ⅱ号线B标岩土工程勘察为例,不仅总结了B标岩土的一些总体工程特征及有关参数的统计数据,为结构设计、降水设计提供了必要的依据;而且在方法上也可为西安地铁岩土工程勘察提供借鉴。同时,这些岩土工程特征及岩土参数,还可为西安城区同类或相似场地岩土工程设计提供参考,也可为丰富西安市城市环境地质内容提供补充资料。

Metro engineering requires a great variety of geotechnical parameters, which can be obtained eilher from laboratory tests or in-situ tests. Using the geotechnical investigation of lot B of line 2 of the Xi＇an Rapid Urban Mass Transit as an example, this article not only summarizes the general characteristics of geotechnical engineering and rel-evant statistics about geoteehnieal parameters of lot B, whieh serves as essential evidence for the structural design and the dewatering design, but also provides a reference for the Xi＇an metro engineering exploration methodologically.Meanwhile, these geotechnical engineering characteristics and parameters can also be used as a reference for the geoteehnical design of similar sites in Xi＇an.
