摘　　要：以福州地铁为例,研究了多种原位测试方法获取地基土基床系数的原理和测试成果,通过对比多个试验的实施条件和结果可靠性等因素,综合得出福州地铁基床系数原位试验中优劣排序为:扁铲侧胀试验法>静力触探法>K30试验法>预钻式旁压法>标准贯入法。通过对比各项试验数据,得出各类原位测试方法适合于福州地区的修正公式和修正系数。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 data,developed correction formulas and coefficients suitable for various in-situ testing methods in Fuzhou area are proposed.
