FAILURE OF THE PILE IS CONSIDERED WHEN THE

DEFLECTION CURVE EXCEEDS THE LIMITS OF ELASTIC

SHORTENING (PL/AE) PLUS 10% OF THE AVERAGE

FLIGHT DIAMETER OR PLUNGING OF THE PILE.

AXIAL TENSION TEST:

IF EXCESSIVE PILE MOVEMENT (I.E. FAILURE) OCCURS

PRIOR TO REACHING THE MAXIMUM ANTICIPATED TEST

LOAD UNDER TENSION LOADING OR PLUNGING AS

DEFINED AS CONTINUED MOVEMENT OF THE PILE

WITHOUT THE ABILITY TO SUPPORT THE LOAD.

FAILURE OF THE PILE IS CONSIDERED WHEN THE

DEFLECTION CURVE EXCEEDS THE LIMITS OF ELASTIC

SHORTENING (PL/AE) PLUS 10% OF THE AVERAGE

FLIGHT DIAMETER OR PLUNGING OF THE PILE.

LATERAL TEST:

IF EXCESSIVE PILE MOVEMENT (I.E. FAILURE) OCCURS

PRIOR TO REACHING THE MAXIMUM ANTICIPATED TEST

LOAD UNDER LATERAL LOADING, CONTINUE JACKING

THE PILE UNTIL THE TOTAL LATERAL MOVEMENT

EQUALS 2 INCHES.

FAILURE OF THE PILE IS DETERMINED THROUGH

ANALYSIS OF THE TEST RESULTS WHEN COMPARED TO

THE ADJUSTED SOIL MODEL IN LPILE.
