Abstract：Based on the statistical relationships of the number of standard penetration test (SPT) with the standard value of utmost lateral friction ( ) and standard value of utmost tip resistance ( ) of piles，and SPT number with shear wave velocity ( )，the interrelated models of with and in the soil around pile is established. Using the technique of transient surface wave test，the shear wave velocity in different depth below the ground can be obtained rapidly. So，a new method of transient surface wave test technique is put forward to predict the bearing capacity of friction pile. Model pile essay and practical engineering application indicate that this method has favorable application foreground.
