| 摘 要： | 在分析复合土钉支护侧土压力分布模式及相关国内外著名实测结果的基础上,考虑基坑底面受开挖影响的深度,提出一种新型的侧土压分布改进模式,即“五边形”模型,并将此模型应用于某水泥搅拌桩复合土钉支护工程中。计算结果表明,所提出的“五边形”侧土压力分布模式与实测结果相符合,与现有的侧土压力分布模式相比更加合理,对复合土钉支护结构的整体设计、稳定性分析、工程造价预算等具有指导意义和应用价值。

| Abstract: | A pentagon model,a new model for the distribution of lateral soil pressure was proposed based on the analysis of presently available models and consideration of foundation pit depth affected by excavation.The calculated results obtained by available models show that The pentagon model for the distribution of lateral soil pressure is of significance to design,stability analysis and cost budget of composite soil nail bracing structure. |
