摘要
南昌朝阳大桥极限承载力100 400 kN试桩采用自反力平衡静载技术,它是江西省目前最大桩基检测项目,在该项工作中,荷载箱埋设离桩底2 m处;所建立的有限元模型模拟了荷载箱、下浇混凝土柱及持力层岩土的共同作用,测试值与理论值吻合良好。
Static load test technology of Reflexive force balance was adopted in the tested pile with maximum load 100400kN, which is the largest project of pile foundation test in Jiangxi province currently. In this work, the load box is buried in 2m from the pile bottom. The finite element model established was simulate interaction of load box, lower pouring concrete column and bearing rock and soil. The test values are in good agreement with the theoretical values.
