基坑支护中旋喷搅拌加筋斜桩锚承载破坏机理研究

摘要

在公路工程项目建设过程中，基坑的应用越来越多。作为一种新型基坑支护结构，旋喷搅拌加筋斜桩锚可大副度提高单位长度锚索的承载能力，有效降低锚索的设计长度，避免因锚索承载能力设计过长而对周边环境造成影响，具有良好的推广应用前景。为了深入研究其承载破坏机理，通过建立和推导旋喷搅拌加筋斜桩锚的力学模型和计算公式，并结合工程实例验证该计算理论与公式的合理性。研究成果可以为该支护结构的工程设计研究人员提供有益参考。%Reinforced inclined pile anchor with rotary jet mixing has been widely used during the highway engineering construction project.As a new type of retaining structure,reinforced inclined pile an-chor with jet mixing can greatly improve the bearing capacity of anchor cable per unit length,reduce the length of anchor design,avoid the impact on the surrounding environment,and has a good application prospect.In order to study the bearing mechanism of reinforced inclined pile anchor with jet mixing,the mechanical model and the calculation formula of the bearing capacity of the oblique pile anchor are estab-lished.The research results can provide useful reference for the engineering design of the supporting structure.
