What is static load test on pile?
Static Load Tests measure the response of a pile under an applied load and are the most accurate method for determining pile capacities. They can determine the ultimate failure load of a foundation pile and determine its capacity to support the load without excessive or continuous displacement.
How a load test for a pile is carried out?
Static pile load testing The test procedure is based on the direct measurement of pile head displacement in response to a physically applied load. The test pile is loaded using a calibrated hydraulic jack that applies the test load to the pile by pushing against a beam placed directly over the test pile.
How many piles are required for static load testing (# of test piles?
The standard plan note for a static load test requires the contractor to drive four piles not including the anchor piles. The first two driven piles are test piles. Each one is driven to the required UBV, as determined by the dynamic load test.
What is an example of static load?
A good example of a static load is the weight of a building acting on the ground. Another example is a car parked at a carpark. A good example of a dynamic load is the weight of a moving car on the road. Click on the following for more illustrations.
What are the types of pile load test?
There are essentially two main types of pile load tests: the preliminary pile test and the working pile test. A preliminary pile test is typically carried out before the piling works commence while the working pile test is carried out during piling or when substantial piling works are completed.
Which two of the following are examples of static loading?
Static loads do not generate any blow or shaking on the building. The examples of this load are car parked at a carpark, the weight of building acting on the surface of the ground, and the force acting on a beam.
What are examples of dynamic loads?
Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading.
