Abstract：The cone penetration test technology with inclination and pore water pressure measurement functions is applied in
the sea-crossing bridge construction subsurface investigation，the offshore CPT operation and also test results are analyzed
and compared with the normal probe head CPT data，stratification and pile load tests. It is found helpful for dividing soil layers
and correcting the soil layer depths though using probe head equipped with inclination and pore water pressure measurement
function，and it is much intuitive to estimate pile foundation bearing capacity or judge the engineering geological properties of
the foundation soil though using CPT in offshore exploration.
