Dynamic Load Testing for Foundation Bearing Capacity

The Pile Load Test is the most reliable method of determining the load carrying of a pile This test can be performed either on a wor Static pile load testing is one of the most common methods for testing the actual in situ capacity of a pile The test program involves the direct measurement of pile head displacement in response to a physically applied load Piles can be Title of Legally Binding Document Guide for lateral dynamic load test on piles Number of Amendments Equivalence Superceding Superceded by LEGALLY BINDING DOCUMENT Step Out From the Old to the New Jawaharlal Nehru Invent a new India using knowledge Satyanarayan Gangaram Pitroda Addeddate 2013 09 12 02 19 43 Identifier 15 08 2020 nbsp 0183 32 Dynamic testing involves attaching two strain transducers and two accelerometers to the pile approximately 1 5 pile diameters below the pile head during initial driving or at a convenient location during re strike testing An impact hammer or a heavy guided block is dropped onto the specially prepared pile head Fig Vertical load test on piles Pile Head The pile head shall be chipped off till sound concrete is met wherever applicable The reinforcement shall be cut and head levelled with Plaster of Paris A bearing plate with a hole shall be placed on the head for the jack to rest Reaction Kentledge shall be suitably designed to get the desired reaction on the piles Anchor piles if required 30 09 2013 nbsp 0183 32 In general two types of pile load tests are conducted They are The initial test is performed before the start of construction to assess the design adequacy The routine test is performed on a working pile This test is also known as work test In initial test the test load 5 2 times the working load in work test load is 3 2 times the design
