HORIZONTAL MOVEMENTS RELATED TO SUBSIDENCE

A REVIEW OF MANY DOCUMENTED FIELD EXAMPLES SHOWS THAT HORIZONTAL SURFACE MOVEMENTS OFTEN ACCOMPANY VERTICAL SUBSIDENCE AND THAT, ALTHOUGH THESE MOVEMENTS MAY RESULT FROM A WIDE VARIETY OF DIFFERENT SITUATIONS, THEY ALL APPEAR TO FOLLOW A WELL DEFINED PATTERN. THIS PATTERN IS THE SAME FOR HORIZONTAL MOVEMENTS ASSOCIATED WITH MINING SUBSIDENCE, SUBSIDENCE DUE TO GAS, OIL OR WATER PUMPING, OR SUBSIDENCE DUE TO DEEP CONSOLIDATION UNDER A HEAVY FILL LOAD SUCH AS AT AN INDUSTRIAL DEVELOPMENT OR AN EARTH DAM. A SEMI-EMPIRICAL AND SIMPLE EQUATION IS PRESENTED WHICH APPEARS TO PREDICT THE NATURE AND MAGNITUDE OF HORIZONTAL MOVEMENTS CORRECTLY, PROVIDED THE VERTICAL SUBSIDENCE PROFILE IS KNOWN. AN APPLICATION OF THE FINITE-ELEMENT METHOD OF ANALYSIS IN COMPUTING BOTH VERTICAL AND HORIZONTAL MOVEMENT IS ALSO ILLUSTRATED. THE RESULTS OF THE TWO METHODS ARE COMPARED TO DATA OBTAINED FROM A LABORATORY MODEL, A HYPOTHETICAL EARTH DAM ON A COMPRESSIBLE FOUNDATION, AND AN ACTUAL ROCKFILL DAM WHICH SETTLED AS THE WATER LEVEL ROSE IN THE RESERVOIR. /ASCE/
