A Study on Program for the Spring Element and the Parameters of Soil Spring Model on the Buried Pipeline

In this project, the main object of this study is to add the numerical codes into the multi-physics coupling simulation platform(MPCSP) in NCREE. Adding codes in MPCSP include the spring element by using the vector form intrinsic finite element(VFIFE) method and ASCE(1984) soil spring model of the buried pipeline. In ASCE(1984) soil spring, two soil parameters such as the soil cohesion and friction angle need to be determined. In this study, in order to easy to use soil spring model, the standard penetration test and empirical formula from experimental data can be used to compute two soil parameters. In addition, the applicability of empirical formula, the results of the geological drilling data from NCREE are compared to the results of the empirical formula.
