摘要
提出了一种改进的双排桩计算模型,基于《基坑工程手册》中的算例,通过与平面计算模型对比验证了改进的双排桩计算模型的合理性,并分析了双排桩的工作性状。通过进一步的参数分析以及与平面应变有限元模型计算结果比较分析,研究了桩间土的刚度和桩间距对计算结果的影响。研究表明:改进的计算模型双排桩受力、变形合理,适合用于双排桩工程的设计和计算。
An improved calculation model of double-row piles is submitted. Based on the case of 'Excavation Engineering Handbook', the rationality of the improved calculation model was verified by compared with the 2D finite element model. The behavior of double-row piles is also analyzed.Through further parameter analysis and comparative analyse with calculative result of finite element model, the influence of the stiffness of the soil and the distance of two piles on calculation results are studied The results show that the improved calculation model is suitable for the design and calculation of double-row pile engineering.
