It is found that the results of large scale triaxial compression tests,confined-uniaxial compression tests and seepage tests for twice on three kinds of rockfills are very closer.

In order to evaluate and treat the engineering mechanics properties of silt soil filled in foundation of highway, a series of laboratory experiments, such as compaction tests, seepage tests, triaxial tests and microstructure analysis, were studied.

The permeability test with different densities of municipal solid waste(MSW) sampled from a suburban building site of Beijing is introduced.

Compacting test and permeability test is a tried and true detecting method and they are applied in this detection.

By analysis of soil permeability test data of dyke strengthing by desilting,we have obtained soil permeability test data statistical index and distribution rule.

The results of in-situ permeability testing and indoor physical-mechanical testing show that the anti-permeability and strength property of saline soil after treatment have been markedly improved.
