摘要

排架式微型桩组合结构作为边坡防护的一种轻型支挡结构

施工安全便捷

对非常环境适应性强。基于弹性地基梁理论应用的基本条件是土体为稳定体

以及排架式微型桩组合结构对不稳定坡体的改善作用使不同位置的微型桩前抗力条件有所差别

在弹性地基梁理论的基础上

借鉴一般微型桩水平承载力计算的思路

通过不同的m(弹性抗力系数)计算值和桩顶大变形对m值的限定条件

来体现微型桩前其他微型桩的存在对地基反力的贡献。以3种基本计算模型建立排架式微型桩组合结构的计算公式

计算并分析该类桩群的内力及对地震力的特殊反应

为微型桩的设计提供一定的参考依据。

Abstract

The composite structure of row posture micro-piles

as a light-weight protection structure in sideslope protection

has the advantages of safe and quick construction and high adaptability to some special environments.A basic requirement of the elastic foundation-beam theory application is that the foundation shouldbe stable.Because the row posture micro-piles composite structure improves the stability of slope

the resistant forces in front of different positions of micro-piles are different.On the basis of the elastic foundationbeam theory and by using the idea of the general micro-piles horizontal bearing capacity calculation method

the row posture micro-piles advantages are revealed by the different calculated m(the coefficient of rock resistance)values and the limited conditions of pile top large deformation.The computational formula of rowposture micro-pile composite structure is established from three basic calculation models.The special response to seismic force is calculated and analyzed in a practical case

which may provide certain reference forthe micro-piles design.
