Research on hydraulic soil slope frost heaving damage model test

摘要

Frost heaving damage of water conservancy project is widespread. In order to research the failure problems of hydraulic soil slope in dark seasonal frozen soil region, laboratory model test is carried out combined with field test section practical situation, which is the prototype of this model test. It is researched that the rule of frost heave parameters variation and the damage of soil slope during freeze-thaw cycling. That offers theoretical basis and reference for construction of water conservancy project, which will mitigate the effect and damage of freeze-thaw on hydraulic soil slope stability.
