平衡拱 [píng héng gǒng]
balanced arch
- 本文主要对桩网复合地基的加固机理进行分析，并结合自然平衡拱理论和加筋垫层拉膜效应理论推导出路堤下桩网复合地基桩土应力比计算公式，同时分析了各设计参数变化对桩土应力比的变化规律。
This article analyses the reinforcement mechanism of pile-net composite foundation mainly, combining natural equilibrium arch theory and reinforced cushion tension membrane theory to deduce the calculation formula of the stress ratio of pile-soil in the pile-net composite foundation under embankment. - 摘要考虑抗滑桩桩间土拱效应，以桩侧与边坡土体间的摩阻力及黏着力承担滑坡推力的静力平衡条件和土拱跨中与拱脚处截面的强度条件共同控制，建立了抗桩间距的计算公式。
In consideration of the soil arch effect between anti-slide piles, a calculation formula for the anti-slide pile spacing was developed, taking the following factors as the controlling conditions-the static equilibrium equation of the frictional resistance and adhesive force between the side of piles and slope soil, which sustains the thrusting force of the landside, and the strength conditions at the medial cross-section and two end sections of soil arch. - 同时，为在设计时考虑减小拱脚不平衡推力这一因素，提出了基于敏感性分析的首控截面应力双控设计法、首控拱脚净推力双控设计法以及直接利用优化理论进行设计等3种合理优化设计方法。
In order to consider the reduction of the thrust at springer, three optimization design methods, i.e. method by firstly controlling stress of section based on sensitivity analysis, method by firstly controlling thrust at springer based on sensitivity analysis, and design method based on optimum theory, are suggested.
