Analysis on Dynamic and Static Test of Vertical Load Capacity

Based on the result of high strain dynamic test and static load test in the same project, the selection of design and construction technology of pile foundation should consider the effect of specific geological condition, calculation value should be selected reasonably according to the real value after the pile-forming, or the fault will turn out. How to use the test method should also be pay attention during the test, for example, dynamic method doesn't fit the friction cast-in-place pile with a gentle Q-s curve; if the supporting soil layer on the pile end which becoming softer when meets water, only slow maintaining load method should be selected when using the static load test, using speed maintaining load method may get the wrong sow by the ear.
