The Study on the Change of Sheer Strength Characteristic Parameter and Soil Nail Firmness of Effect in the Condition of Freezing-Thaw Cycling

Abstract:

By fine earth freeze-thaw simulated experiment and cut experiment in the room, this paper studied the sheer strength characteristic parameter before and after the freezing-thaw cycling, and got the change discipline of the internal cohesive force c, internal friction angle Ф in the different temperature range and the number of the freezing-thaw cycling, deduced the calculation formula of c, Ф and T(soil nail counteract evulsion force) according to the experiment data, and compared the effect of the firmness.
