在盐湖地区除有很厚的岩盐层外,砂、砾石及非盐土壤和淡水资源极度匮乏,因此,此类地区公路建设中如何合理利用资源,充分利用当地土壤的特性并选择适宜的施工工艺筑路,达到满足使用要求和降低工程造价的目的,无疑具有极大的社会效益和经济效益。通过对罗布泊干涸湖区岩盐的物理、化学成份、力学特性的试验分析,提出了结合料强度与易溶盐含量、压实度的关系及路用指标,并应用于工程实际。
In addition to the thick salt rock layer in the Salt Lake region, sand, gravel and non-salt soil and fresh water resources are extremely scarce, so how to rational use of resources in highway construction in this area, make full use of the characteristics of local soil and choose the appropriate construction technology Road construction, to meet the requirements and reduce the cost of construction purposes, will undoubtedly have great social and economic benefits. Through the analysis of the physical, chemical composition and mechanical properties of rock salt in the dry lake area of Lop Nur, the relationship between bond strength, soluble salt content and compaction degree as well as the road index are put forward and applied to engineering practice.
