THE ANCHOR MOVEMENTS SHALL BE MEASURED FROM THE INITIAL ALIGNMENT LOAD AND RECORDED TO THE NEAREST .001 INCHES WITH RESPECT TO AN INDEPENDENT FIXED REFERENCE POINT AT THE ALIGNMENT LOAD AND AT EACH INCREMENT OF LOAD. THE ALIGNMENT LOAD 15 A NOMINAL LOAD MAINTAINED ON THE SOIL ANCHOR TO KEEP THE TESTING EQUIPMENT IN POSITION. 3. THE TEST LOAD SHALL BE MONITORED WITH A PRESSURE GAUGE. A REFERENCE GAUGE SHALL BE PLACED IN A SERIES WITH THE PRE55ME GAUGE DURING EACH PERFORMANCE TEST. IF THE REFERENCE PRESSURE GAUGE AND THE PRESSURE GAUGE READINGS DIFFER BY MORE THAN 10 PERCENT: THE JACK, PRESSURE CAUGE. AND REFERENCE GAUGE SHALL BE RECALIaRATED. AT LOAD INCREMENTS OTHER THAN THE MAXIMUM LOAD. THE LOAD SHALL BE HELD JUST LONG ENOUGH TO OBTAIN THE MOVEMENT READING, BUT NO MORE THAN ONE MINUTE. 4. THE PUMP SHALL BE CAPABLE OF APPLYING EACH LOAD INCREMENT IN LESS THAN 60 SECONDS. 5. THE WIMUM TEST LOAD 1N A PERFORMANCE TEST SHALL BE HELD FOR 10 MINUTES. THE ANCHOR MOVEMENT WITH RESPECT TO A FIXED REFERENCE SHALL BE MEASURED AND RECORDED AT 1 MINUTE, 2, 3, 4. 5. 6 AND 10 MINUTES. IF THE ANCHOR MOVEMENT BETNEENI MINUTE AND 10 MINUTES EXCEEDS 0.04 INCHES, THE MAXIMUM TEST LOAD SHALL BE HELD FOR AN ADDITIONAL 50 MINUTES. IF THE LOAD HOLD IS EXTENDED. THE ANCHOR MOVEMENT SHALL BE RECORDED AT 15 MINUTES. 20, 25. 30, 45 AND 60 MINUTES. THE LOAD HOLD 114E SHALL BEGIN WHEN THE PUMP STARTS TO RAISE THE LOAD FROM THE 1.200L LOAD INCREMENT TO THE 1.330E LOAD INCREMENT, 6. LOCK -OFF THE LOAD AT 100% OF THE DESIGN LOAD UNLESS NOTED OTHERWISE. (SEE THE GROIN ANCHOR SUMMARY TABLE,) 7. PLOT THE ANCHOR MOVEMENT VERSUS LOAD FOR EACH LUAU INCREMENT MARKED WITH AN ASTERISK Is) IN THE PERFORMANCE TEST SCHEDULE AND PLOT THE RESIDUAL MOVEMENT OF THE ANCHOR AT EACH ALIGNMENT LOAD VERSUS THE HIGHEST PREVIOUSLY APPLIED LOAD. GRAPH FORMAT SHALL BE APPROVED BY THE ENGINEER PRIOR TO USE, 8. A PERFORMANCE TESTED GROUND ANCHOR WITH A 10 MINUTE LOAD HOLD IS ACCEPTABLE IF: a. THE ANCHOR WILL CARRY THE MAXIMUM TEST LOAD WITH LESS THAN 0.04 INCHES OF MOVEMENT OETNEEN 1 MINUTE AND 10 MINUTES, AND b. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD EXCEEDS 80 PERCENT OF THE THEORETICAL ELASTIC ELONGATION OF THE UNBONDEO LENGTH. AND c. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD DOES NOT EXCEED THE THEORETICAL ELASTIC ELONGATION OF THE UNBOWED LENGTH PLUS 50% OF THE THEORETICAL ELASTIC ELONGATION OF THE 813NDED LENGTH. 9. A PERFORMANCE TESTED GROUND ANCHOR WITH A 60 MINUTE LOAD HOLD IS ACCEPTABLE IF: a. THE ANCHOR WILL CARRY THE MAXIMUM TEST LOAD WITH LESS THAN 0.00 INCHES OF MOVEMENT BETWEEN 6 MINUTES AND 60 MINUTES, AND b, THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD EXCEEDS 80 PERCENT OF THE THEORETICAL ELASTIC ELONGATION OF THE UNDONOED LENGTH, AND c. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD DOES NOT EXCEED THE THEORETICAL ELASTIC ELONGATION OF THE UNBONOED tENGTH PLUS 50% OF THE THEORETICAL ELASTIC ELONGATION OF THE BONDED LENGTH. IO.

THE ANCHOR MOVEMENTS SHALL BE MEASURED FROM THE INITIAL ALIGNMENT LOAD AND RECORDED TO THE NEAREST .001 INCHES WITH RESPECT TO AN INDEPENDENT FIXED REFERENCE POINT AT THE ALIGNMENT LOAD AND AT EACH INCREMENT OF LOAD. THE ALIGNMENT LOAD IS A NOMINAL LOAD MAINTAINED ON THE ANCHOR TO KEEP THE TESTING EQUIPMENT IN POSITION. 3. THE TEST LOAD SHALL BE MONITORED WITH A PRESSURE GAUGE. AT LOAD INCREMENTS OTHER THAN THE MANIMUM TEST LOAD, THE LOAD SHALL BE HELD JUST LONG ENOUGH TO OBTAIN THE MOVEMENT READING, BUT NOT MORE THAN DNE MINUTE. A. THE PUMP SHALL BE CAPABLE OF APPLYING EACH LOAD INCREMENT IN LESS THAN 60 SECOHOS. 5. THE MAXIMUM TEST LOAD IN A PROOF TEST SHALL BE HELD FOR 10 MINUTES, THE ANCHOR MOVEMENT WITH REPPECT TO A FIXED REFERENCE SHALL BE MEASURED AND RECORDED AT 1 MINUTE. 2. 3. 4. 5. 6 AND 10 MINUTES. IF THE ANCHOR MOVEMENT BETWEEN 1 MINUTE AND 10 MINUTES EXCEEDS 0.04 INCHES, THE MAXIMUM TEST LOAD SHALL BE HELD FOR AN ADDITIONAL 50 MINUTES. IF THE LOAD HOLD 15 EXTENDEOI THE ANCHOR MOVEMENT SHALL RE RECORDED AT 15 MINUTES, 20, 25, 30, 45 AND 60 MINUTES. THE LOAD HOLD TIME SHALL BEGIN WHEN THE PUMP STARTS TO RAISE THE LOAD FROM THE 1.20DL LOAD INCREMENT TO THE 1.33DL LOAD INCREMENT. G. LOCK -OFF THE LOAD AT 100% OF THE DESIGN LOAD UNLESS NOTED OTHERWISE. SSEE THE GROUND ANCHOR SUMMARY TABLE., 7. PLOT IRE ANCHOR MOVEMENT VERSUS LOAD FOR EACH LOAD INCREMENT GRAPH FORMAT SHALL BE APPROVED BY THE ENGINEER PRIOR TO USE. 8. A PROOF TESTED GROUND ANCHOR WITH A 10 MINUTE LOAD HOLD IS ACCEPTABLE IF: a. THE ANCHOR WILL CARRY THE MAXIMUM TEST LOAD WITH LESS THAN 0.94 INCHES OF MOVEMENT BETWEEN 1 MINUTE AND 10 MINUTES, AND b. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD EXCEEDS 80 PERCENT OF THE THEORETICAL ELASTIC ELONGATION OF THE UNBOWED LENGTH, AND c. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD DOES NOT EXCEED THE THEORETICAL ELASTIC ELONGATION OF THE UNBONQEn LENGTH PLUS 50% OF THE THEORETICAL ELASTIC ELONGATION OF THE BONDED LENGTH. A PROOF TESTED GROUND ANCHOR WITH A 60 MINUTE LDAO HOLD IS ACCEPTABLE IF: a. THE ANCHOR WILL CARRY THE MAXIMUM TEST LOAD WITH LESS THAN 0.08 INCHES OF MOVEMENT BETWEEN 6 MINUTES AND 60 MINUTES. AND b. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD EXCEEDS 80 PERCENT OF THE THEORETICAL ELASTIC ELONGATION OF THE UNBDNOED LENGTH. AND c. THE TOTAL MOVEMENT AT THE MAXIMUM TEST LOAD DOES NOT EXCEED THE THEORETICAL ELASTIC ELONGATION OF THE UNBONDED LENGTH PLUS 50% OF THE THEORETICAL ELASTIC ELONGATION OF THE BONDED LENGTH. 10.
