Systematic physio-mechanical properties test and analysis, especially analysis of relationship between expansion rate, dry density, water content, and overlying pressure, are carried out.
为了提高土壤容重测定中土样采集的效率和精准性,将环刀法和原状取土管法结合,进行了分段式原状取土器的研制。
To improve efficiency and veracity of soil sampling in testing bulk density, the cutting ring method and in situ soil tube method were combined and a multi-segment in situ soil sampler was designed.
干容重越大,土骨架能够承受荷载的有效面积越大,冻土的强度也越大。
The greater the dry density is, the greater the load bearing area of soil particles is, and the greater the strength of frozen soil will be.
