Experimental Study on Bearing Behavior of Large-Diameter Overlength Cast-in-Place Bored Pile Post-Grouting

Abstract:

The bearing capacity property of large-diameter bored cast-in-situ deep and post-grouting pile is analyzed on the basis of measuring data of static load test and axial stress measure data. The study indicates that the large-diameter bored cast-in-situ deep and post-grouting pile show the characteristics of the friction when the bearing course at pile end is sand, when the pile top load is greater than 18000kN, the pile end begin to resistance and the share proportion is small, only 1% to 10%; the load settlement cure is gradual decline, no inflection point, the settlement of pile compression only accounted for about 15%, The developing degree of side resistance is well corresponding to the relative displacement between pile and soil. The side resistances significantly enhance effect, the measured value of the soil side resistance is 1.3 to 1.5 times of survey report recommended.
