摘要: 利用數值模擬方法對復合錨固樁的加固機理以及其承載性能進行了比較系統的分析,并將復合錨固樁技術成功地應用于多處地基加固工程.數值模擬結果及工程檢測結果均表明:復合錨固樁改善了單根錨固樁樁體局部承載特性,樁體承載綜合有效因子明顯增加,樁體承載能力大大提高.Abstract: The bearing behavior and reinforcement mechanism of a composite bolt pile was studied through numerical calculation with the FLAC soft. The composite bolt pile was successfully used in several ground-reinforcing engineering. The results of numerical simulation and engineering monitoring show that the bearing behavior of the composite bolt pile is improved in comparison with a single bolt pile, the effective factor and bearing capacity of the pile are obviously enhanced.
