Simplified algorithm of frost heaving force in seasonally frozen soil region
ZHANG Li-wei;YU Xing-hua;TENG Kai;
Based on the criterion of code for design of hydraulic structures against ice and freezing action, there are many problems for the unit tangential frost heaving force and unit horizontal frost heaving force showed with table in the practical project application,including the dependent form calculation, great interpolation error and casualness extension values, etc. Through the analysis of linear characteristics of the relation curve between the frost heaving force and frost heaving amount, the mathematical expression with the simple form, rapid sampling process and high calculation accuracy is gained by using the optimization fitting method, which could be applied and extended in practical project.
