    摘要:

    针对基坑工程采用数值分析方法变形计算误差大、准确度低的问题,结合已有监测数据提出了基于GWO-SVR的地层参数反演分析方法,可实现较为精确的基坑变形计算,尤其适用于出现较大变形的基坑。在此基础上研究了相邻对拉锚索基坑开挖过程中出现大变形的原因,对两种不同的变形控制处置措施开展了对比计算,并通过实测数据分析了处置措施的有效性。对拉锚索基坑间距选取对于基坑稳定性及支护结构受力有较大的影响,采用数值分析方法,提出了不同基坑间距条件下基坑支护桩变形与内力、锚索力以及桩间土压力的变化规律,可实现对拉锚索基坑在不同间距条件下支护结构的差异化设计,为对拉锚索基坑的选型与计算分析提供参考。

    Abstract:

    Aiming at the problems of large deformation calculation errors and low accuracy in numerical analysis methods for foundation pit engineering,a geological parameter inversion analysis method based on GWO-SVR is proposed in combination with existing monitoring data,which can achieve more accurate deformation calculation of foundation pits,especially suitable for foundation pits with significant deformation.On this basis,the causes of large deformation during the excavation process of adjacent anchor cable foundation pits are studied,and two different deformation control measures are compared and calculated.The effectiveness of the treatment measures is analyzed through measured data.The selection of the spacing between anchor cable foundation pits has a significant impact on the stability of the foundation pit and the stress of the supporting structure.By using numerical analysis methods,the deformation and internal forces of the foundation pit support piles,anchor cable forces,and soil pressure between piles under different spacing conditions are proposed.This can achieve differentiated design of the supporting structure for anchor cable foundation pits under different spacing conditions,providing reference for the selection and calculation analysis of anchor cable foundation pits.
