Application of Strain Measurement in Marine Pile Static Load Test

In situ test is the most reliable and objective way to obtain pile design parameters and realize pile mechanical property.During the marine pile static load test,strain measurement may be carried out simultaneously through the electric resistance strain chip mounted on steel pipe pile.The strain values of axial forces of piles in different strata may be measured.By analyzing the law of load transmission between pile and soil layer,the following can be obtained,i.e.the pile side frictional resistances,pile tip bearing capacities and flexural moment distribution of pile under horizontal load in different strata.
