Abstract:

Inshore saline soil is a special soil which has some bad engineering properties, such as collapse, dilatability and erosion etc. Filling material of highway subgrade with saline soil is one of the important geotechnical engineering challages, which restricts the development of highway in inshore saline area. In order to solve the engineering application of the saline soil in inshore area, large numbers of tests are done. The tests include the liquid and plastic limits test, compaction test, CBR test and unconsolidated-undrained triaxial test. The feasibility of improved saline soil for inshore subgrade filling material is discussed according to the engineering technique, cost and environment protecting. This conclusions give a reference to the construction of inshore area saline soil highway subgrade.

Key words: calcium carbide dust, improvement, saline soil subgrade, test
