Research on Foundation Coefficient of Fuzhou Metro Based on Multiple In-situ Testing Methods
Taking Fuzhou Metro as an example,this article focuses on studying the principles and test results of various in-situ testing methods to get foundation coefficient.By comparing the implementation conditions and result reliability of multiple experiments,the ranking of the advantages and disadvantages of multiple in-situ tests is as follows:flat shovel lateral expansion test method>static cone penetration test method>K30 test method>pre-drilling test lateral pressure>standard penetration testing.While comparing various experimental da-ta,developed correction formulas and coefficients suitable for various in-situ testing methods in Fuzhou area are proposed.
