Discussions Of The Quality Controlling And The Detecting Method Of Embankment With Soil-Rock Mixture

The paper combines the question of the embankment grinded with soil-rock mixture in construction, summarizes and discusses the data and experience in test and in construction with the mixture. So the view comes into being:(1) The paper brings forward the mathematic method determining the parameter of the mixture grinded—forecasting method of Grey System Theory. Namely, after test road, the Grey System Theory will be brought into data processing to forecast the settlement, consequently the appropriate parameters are determined, and the parameters determining become scientific.(2) The detecting method of the embankment with shear-wave is brought forward after comparing deferent detecting methods in road and railway. Its indexes are porosity and dynamic modules of the embankment. And combining the tests in laboratory, a semi-theoretical formula about shear-wave velocity and porosity is discussed.(3) The criterion of porosity in quality controlling is determined.
