An instrumented test pile was planned for Kochi Metro project in order to understand the soil-pile interaction behavior for that Cyclic static load test was planned. Geo Dynamics was engaged for providing and installing strain gages in the pile for instrumentation purpose. Geo Dynamics was also responsible for collecting readings from strain gages during vertical load test. Pile Length was 48m and pile diameter was 2000mm. 56 strain gages were installed. Pile was able to take test load of 1275tons and settlement was about 12mm.
The instrumented pile load test requires expert interpretation and analysis as well as sound knowledge of geotechnical engineering and piling practices. Instrumentation is not limited to data collection and presentation but shall be properly analyzed to make some sense out of it.
