摘要
SMW工法中水泥土对于支护桩体刚度的贡献大小至今没有完整的理论,所以水泥土刚度贡献的研究仍将是以后的重点。SMW工法桩体刚度较小,为柔性支护结构,那么过大的支撑预加轴力及支撑可能对支护桩体局部的变形及内力分布有较大的影响。通过分析水泥土对支护桩刚度的贡献及支撑刚度和预加轴力对基坑变形内力的影响,从而为此类基坑设计及施工提供理论指导作用。
The contribution of cement-soil to pile composite stiffness needs systematic theory,so and it will continue to be the research emphasis in the future. SMW method pile stiffness is generally small and it belongs to a flexible supporting structure.so excessive brace pre axial force and stiffness may have great influence on pile local internal forces and deformations. The analysis of the contribution of cement-soil to pile composite stiffness and the influences of brace on foundation deformations and internal forces can provide theoretical guidance for design and construction of such kind of pit.
