Cause Analysis of Sand Density and Engineering Evaluation

Article Preview

Abstract:

The density of the sand is important factor for its engineering properties, There are many methods to evaluate the sand density, just the results may be differences, usually means, this is the test error of the different test methods. In fact, the reasons of the sand formation and buried conditions, sand particle shape and size, sand gradation, groundwater etc. are also the important factors for its engineering properties, but these factors are often ignored. Bearing pressure of confined water will change the distribution of the effective weight stress in soil and the abnormal phenomenon of sand density will appear. In the project, the cause analysis of sand density require attention. According to theoretical knowledge, to identify applicable conditions of the various evaluation methods and their advantages and shortcomings.
