摘要
根据厚德明挖段钢板桩支护结构的实测数据的情况,结合GTS有限元模拟分析,对钢板桩支护结构的实测值和计算值进行对比。得出以下两个问题:①钢板桩单独受力和整体紧扣受力相对位移变形比较;②围檩和支撑构件对钢板桩受力变形的贡献,并且为钢板桩的预警值提供参考值。在进行MIDAS有限元分析时,采用莫尔-库伦破坏准则的理想弹塑性本构模型考虑土的弹塑性性质。
In this paper, according to the measured data of Hou De digging section steel sheet pile supporting structure, combined with GTS finite element simulation analysis of sheet pile retaining structure, the measured values and the calculated values are compared. There are two following problems： firstly, the difference between Steel sheet pile singly stress and whole closely in relative displacement deformation stress; secondly, Cross-beam and a supporting member on steel sheet pile deformation contribution And proposed for steel sheet pile warning value reference value. In MIDAS finite element analysis, considered soil elastoplastic properties in using Mohr - Coulomb failure criterion of the ideal elastic-plastic constitutive model.
