Study on Loess Structure with Different Test Methods

Research purposes:Loess is a special quaternary continental deposit with typical structural soil,and its special structure directly affects the characteristics of engineering mechanics of loess.With continuous developments of the economy and construction in China,the project quantity and scale in loess region increase day by day.The engineering accidents caused by the loess happens sometimes,so the study on the loess structure has a practical significance. Research conclusions:(1) The change pressure affected the loess structure.The compaction arose by pressure made reduced the changeability of loess structure and the stability of structure increased.(2) The change water content affected the loess structure.The structural parameter reduced with the increasing of water content.At the same time,both have nearly relationship.The pressure was lower,the damage of loess structure is smaller.(3) Both of the pressure and water could cause the damage to the loess structure,but the damage level was different.
