Analysis and evaluation of soil liquefaction by double bridge cone penetration test on Tianjin metro

Jiang Qi;  
Through discussing the comprehensive tests of the double bridge cone penetration test, the standard penetration test, and the comprehensive drilling sampling test for 14 workplaces in the Tianjin metro construction project, this paper analyzes the relationship between the resistance qc of the cone point, the friction-resistance ratio Rf and the clay content ρc, and puts forward the Rf and ρc linear relation formula. Meanwhile it evaluates soil liquefaction of the existing workplaces by using the double bridge cone penetration test method.
