摘要
运用打桩波动模拟方法,结合地质分析,以最终贯入度、总锤击数,承载力大小、持力层厚度、下卧层厚度和性质等指标定量地得出了某大型桥梁大直径预应力管桩的持力层和桩长,分析结果为大桥基础的设计提供了合理依据。
By use of the pile wave equation simulation with the geological analysis method, the supporting stratum of pile end and pile length of large diameter PHC tubular piles were obtained for a large bridge project on the basis of the pile penetration, the total number of blows, bearing capacity, thickness of supporting stratum, thickness and characters of soil stratum underneath supporting stratum. These results have provided reasonable evidences for the foundation design of the bridge.
