To improve efficiency and veracity of soil sampling in testing bulk density, the cutting ring method and insitusoil tube method were combined and a multi-segment insitusoil sampler was designed.
Research shows that in-situ test methods reflect the engineering properties of the soil more objectively and serve the survey and design of the excavation engineering better.
