Introduction The cast-in-situ foamed lightweight soil is a kind of artificial geotechnical material.
It is a lightweight filling material, in the process of which, cement, water and raw materials for the soil are fully mixed into a slurry by a certain percentage, and then fully mixed with a certain percentage of weeny stable bubble group to stir into a fluid, which is finally solidified into a fixed form [1].
In the action of certain dynamic stress amplitude, the vibration times required for the material damage can be expressed by the relationship curve between the dynamic stress and the corresponding failure vibration times, which is called dynamic strength of the material curve.

In recent years, because of the serious environmental problem, how to make greater use of renewable plant resources to produce chemicals and materials, causes the attention of scientific and industrial community all over the world.
Guar gum was used as raw material to prepare galacto-mannan-oligosaccharides (GMOS) using β- mannanase [13].
Summary Galactomannan gums acquired from plant resources are rich in sources of the raw materials and have unique physical-chemical characteristics, so as to be applied widely in many industrials.
These studies investigated structure-activity relationship, functional materials preparation, special modified chemicals of plant galactomannan gums, which can establish theoretical basis for comprehensive utilization of plant galactomannan gums.
