USE OF PORE-PRESSURE MEASUREMENT TO CONTROL EMBANKMENT CONSTRUCTION

THE STABILITY OF THREE ROAD EMBANKMENTS HAS BEEN ASSESSED AGAINST FAILURE ALONG BOTH CIRCULAR AND NON-CIRCULAR SURFACES. EXAMPLES ARE GIVEN OF SITE-CONTROL CHARTS, BASED ON THESE ANALYSES, WHICH RELATE THE FACTOR OF SAFETY TO THE PERCENTAGE DISSIPATION OF EXCESS PORE-WATER PRESSURE. SITE CHECKS ON STABILITY USING THESE CHARTS ARE COMPARED WITH THE RESULTS OF UP-DATED ANALYSES BASED ON THE ACTUAL FIELD MEASUREMENTS AT CRITICAL STAGES DURING CONSTRUCTON. DETAILED RESULTS OF THE SITE MEASUREMENTS ARE PRESENTED AND COMPARED WITH THE ASSUMPTIONS USED IN THE PREPARATION OF THE CHARTS. IT IS CONCLUDED THAT THE EFFECTIVE-STRESS METHOD OF ANALYSIS, WHEN USED IN CONJUCTION WITH SUITABLE FIELD MEASUREMENTS, PROVIDES A PRACTICAL AND ECONOMIC MEANS OF CONTROLLING STABILITY DURING CONSTRUCTION. /RRL/(A)/
