摘要

水平加筋是广泛应用的软土地基处理方法之一，而水平加筋地基极限承载力的确定是其地基处理设计的重要依据。因此，首先结合条形基础下水平加筋地基的工程特点，在探讨其承载机制和破坏特点的基础上，考虑破坏间断面上筋材与地基土体的变形协调，构建出反映加筋参数变化影响的可变破坏模式及机动允许速度场；然后，在此基础上，通过重点研究筋材的能量耗散分析方法，并引入上限极限分析理论，建立出条形基础下水平加筋地基极限承载力分析模型，再引入序列二次规划优化分析理论，建立出条形基础下水平加筋地基极限承载力确定方法，它能充分反映加筋设计参数对地基破坏模式及承载力的影响；最后，通过试验结果与该方法及现有同类分析模型结果的比较分析，表明了该模型与方法的合理性与可行性。

Abstract

The horizontal reinforcement is a method of ground treatment for soft soil. The calculation of the ultimate bearing capacity of the reinforced grounds is important to the design of ground foundation treatment. Firstly

combined with the engineering characteristics of reinforced grounds

a changeable failure mode varying with the reinforcement parameters and the kinematically admissible velocity field are established by its failure mechanism considering the influence of the coordinate deformation between soil and the horizontal reinforcement. Secondly

with the upper limit analysis

the ultimate bearing capacity calculation was deduced by the method of energy dissipation for the level reinforcement. Thirdly

a new approach for determining the ultimate bearing capacity of the reinforced grounds is introduced by the sequential quadratic programming optimization algorithm. Finally

the comparisons with experimental results find that this proposed method is reasonable

feasible

and superior to other existing methods

also can reflect the reinforcement design parameters effect on the failure mode and its ultimate bearing capacity.
