CLOSURE ON FOUNDATION STUDY FOR MATERIALS TEST STRUCTURE

THE AUTHORS ARE PLEASED THAT THEIR PAPER HAS STIMULATED THE DISCUSSION BY LANGFELDER AND BREWER. AS INDICATED IN THE ORIGINAL PAPER, THEY ARE IN ACCORD WITH ALL OF THE COMMENTS MADE IN THE DISCUSSION EXCEPT FOR THE COMMENTS PERTAINING TO VOID RATIO AND LIQUIDITY INDEX. THE AUTHORS DO WISH TO THANK LANGFELDER AND BREWER FOR THEIR VALUABLE ADDITIONS REGARDING THE USE OF LIQUIDITY INDEX AND VOID RATIO IN THE EQUATION FOR PREDICTING SHEAR STRENGTH. THE PRIMARY OBJECTIVE OF DEVELOPING EQUATIONS FOR PREDICTING SHEAR STRENGTH IS TO UTILIZE INFORMATION OBTAINABLE FROM CORE SAMPLES TAKEN FOR PURPOSE OTHER THAN ENGINEERING INVESTIGATIONS. SUCH SAMPLES MAY BE DISTURBED BY THE SAMPLING PROCESS, BY DESICCATION DUE TO LONG STORAGE, OR FROM OTHER MEANS. BECAUSE THE SAMPLES ARE DISTURBED, IT IS NOT POSSIBLE TO OBTAIN AN ACCURATE VALUE OF VOID RATIO AND ORIGINAL WATER CONTENT AS PROPOSED BY LANGFELDER AND BREWER; THE ORIGINAL WATER CONTENT IS REQUIRED FOR COMPUTING THE LIQUIDITY INDEX. HOWEVER, LANGFELDER AND BREWER'S SUGGESTION OF USING THE LIQUIDITY INDEX PARALLELS A RESEARCH EFFORT UNDERWAY AT THE NAVAL POSTGRADUATE SCHOOL TO DEVELOP A METHOD FOR PREDICTING THE ORIGINAL WATER CONTENT FOR USE IN DETERMINING THE LIQUIDITY INDEX. SINCE THE COST OF OBTAINING SAMPLES FORM THE SEAFLOOR IS HIGH, MAXIMUM USE SHOULD BE MADE OF SAMPLES THAT HAVE BEEN TAKEN FOR OTHER PURPOSES AND WHICH ARE BEING KEPT IN STORAGE. AS ADDITIONAL ENGINEERING DATA ARE COLLECTED, FURTHER CORRELATION ANALYSES ARE ENCOURAGED TO UTILIZE DATA FROM THESE COLLECTED SAMPLES FOR SITE INVESTIGATION PURPOSES. /AUTHOR/
