应用ABAQUS有限元分析软件对影响双排桩支护效果的关键因素进行了数值分析,研究了排距、连梁刚度和被动区土体加固对双排桩影响的规律,结合工程实例,将理论计算结果与实测资料对比分析。结果表明,增大排距、提高连梁刚度和加固被动区土体能有效改善双排桩支护效果,进一步揭示了开挖深度与适宜排距的关系,为双排桩设计施工提供参考。
ABAQUS finite element analysis software is used to analyze the key factors affecting the supporting effect of double-row piles. The influence of row spacing, connecting beam rigidity and soil reinforcement on double-row piles in passive zone is studied. Combined with engineering examples, Comparison between the calculation result and the measured data. The results show that increasing the row spacing, increasing the rigidity of the connecting beam and strengthening the soil in the passive zone can effectively improve the supporting effect of double-row piles. The relationship between the excavation depth and the appropriate row spacing is further revealed, providing reference for the design and construction of double-row piles.
