摘要
以大源河道护岸工程为例,构建了深基坑支护结构模型,并对7类不同工况下的围护桩变形特性进行模拟分析,主要从围护桩水平位移、围护桩竖向位移(围护桩周围地表沉降)、围护桩入土深度与深基坑变形情况的关系等3个方面展开。结果表明,模拟值与实测值相符程度高,所构建模型具有较高合理性;围护桩水平变形、竖向变形(地表沉降)与围护桩入土深度存在线性关系,在工程实践中需要精确计算并选择适当的入土深度。
Using source of river revetment engineering as an example,the first member of the deep foundation pit supporting structure model. Then,seven kinds of different conditions of retaining pile deformation characteristics are simulated and analyzed,mainly from the horizontal displacement of retaining piles,retaining pile vertical displacement( envelope around the pile surface settlement),buried depth of supporting pile and deep foundation pit deformation of the relationship between the three aspects. The results show that simulation results agreed well with the measured value degree is high,the constructed model has higher rationality; retaining pile horizontal deformation and vertical deformation( settlement) has a linear relationship with a buried depth of retaining piles,the accurate calculating and selecting appropriate buried depth in engineering practice.
