Instrumented Pile Load Tests in Southern India
A conventional vertical static load test on a pile provides limited information as only pile top load and displacement is monitored. Such testing does not provide any quantitative information on the load-transfer mechanism (i.e., magnitude of the toe resistance and the distribution of shaft resistance). Similarly, conventional lateral load test only provides the load–deflection curve for the top of the pile and pile deflection along the length as well as point of fixity is unknown. Yet, this information is what the consultant often needs in order to verify his design. Therefore, more and more frequently, the conventional test arrangement is expanded to include instrumentation to obtain the required information. This paper presents a case study for the instrumented tests performed in Kochi for a Test pile at Kochi Metro Rail Project. Geo Dynamics in association with Kochi Metro Rail Corporation (KMRL) performed state-of-the-art instrumentation studies during vertical as well as lateral load tests. Embedment type strain gages were installed in the pile during pile casting to perform instrumentation study. An inclinometer casing was also installed in order to monitor the deflection of pile along the length during lateral load test. The pile was a test pile (mono pile) with diameter of 2 m and length of 50 m. A crosshole sonic logging (CSL) test was also performed before the load tests for assessment of pile integrity.
