应用高应变动力试桩法确定桩端土的极限承载力是动力触探领域中的一种好方法。运用高应变动力试桩法，可以获得桩在打入过程中的每一锤击下的桩端阻力，即桩端土对桩的端承力。用该力除以桩端的横截面积，即可求得桩端土的极限承载力。结合每一锤的贯入度（或每一锤时桩的入土深度），还可获得桩端土承载力随深度连续变化的测试结果
The application of high-strain dynamic test piles to determine the ultimate bearing capacity of the soil at the pile tip is a good method in the field of dynamic penetration testing. Using the high-strain dynamic trial pile method, the pile end resistance under each hammering of the pile in the driving process can be obtained, that is, the end bearing capacity of the pile end soil to the pile. By dividing this force by the cross-sectional area of the pile end, the ultimate bearing capacity of the soil at the pile end can be determined. Combining the penetration of each hammer (or the depth of penetration of the pile per hammer), the test results of the continuous change of the bearing capacity of the pile tip with depth can also be obtained.
