Case Study on Soft Foundation of Coastal Saline Soil

Article Preview

Abstract:

Coastal saline soil foundation was consolidated by surcharge preloading method based on the improving constructio technol-ogy. For instance,setting sand gravels separation layer,composite geo-membrane separation layer,improve embankment height, etc. The monitoring results are analyzed including the ground with every soil layer settlement. Combining with the test result of the shear strength of vane shear test and various ion content of soil samples,it is concluded that reinforcement effect of seashore saline soil consolidated by surcharge preloading method,at the same time, exclusion salt and reduce damage of the foundation.
