Analysis into How to Determine the Spring Constant of Groundwork in Design of Underground Structure
Based on the Winkler's hypothesis, this paper discusses how to determine the spring constant of groundwork in design of underground structure. When no sufficient experimental conditions are available, the method of numerical calculation can be used to determine the value of spring constant of groundwork. The resulted value is basically the same as the value of experience from the engineering criterion.
