摘 要: | 为查明察尔汗盐湖区工程地质情况,依托察格高速公路工程,采用地质勘察、土工试验等手段,提出了该区域工程地质分区:以区域地貌作为工程分区的主要依据,盐湖区分为湖相及化学沉积区、湖相沉积区、滨湖相沉积区3个区;依据岩土物理力学特征,在工程地质分区的基础上划分出工程地质亚区。根据工程实践,介绍了察格高速公路路基阻盐技术。

Engineering Geology Zoning of Salt Lake Area along Qarham-Golmud Highway and the Anti-salt Technology for Subgrade |
| |
Abstract: | In order to look out the engineering geological condition in the Qarham salt lake area,this paper,depending on Qarham-Golmud Highway project,proposed by means of geological survey and geotechnical test the engineering geology zoning,i.e.based on regional landform,the salt lake area is divided into 3 zones,including lacustrine and chemical deposit zone,lacustrine deposit zone and shore-lacustrine deposit zone and then according to the physical and mechanical properties of rock and soil,the sub-zones in terms of engineering geology was divided on the basis of the zoning above.Then depending on the engineering practice,the anti-salt technology for the subgrade thereof was introduced. |
