Due to the complex environment of oceans, present in-situ test methods are of some limitations in obtaining the physical and mechanical properties of undisturbed soil in offshore engineering applications. A novel pull-out cone penetration test (CPT) is proposed to solve the problems. In order to verify the feasibility of this method, we conducted CPT, pressuremeter test, and pull-out CPT and compared the curves of test parameters against depth as in different in -situ test methods. We found that the test result obtained by the pull-out CPT was of similar variation trends with those of other test methods, implying that pull-out resistance is able to reflect soil’s physical and mechanical properties, and that the proposed pull-out CPT is feasible. The research results lay the foundation for further research and application of pull-out CPT.
