| 摘 要： | 在加筋格宾挡墙筋材原型观测试验和数值模拟的基础上,对不同加筋规范所采用的破裂面进行了比较分析,提出了改进双折线型潜在破裂面,并通过加筋格宾挡土墙实体工程的现场观测结果,进一步分析了改进双折线型潜在破裂面的优点。结果表明:采用改进双折线型破裂面计算,比公路规范和BS8006规范安全,比铁路规范经济。采用极限平衡法,推导了双折线型破裂面在拉力破坏和粘着破坏时的墙顶部表面通用承载力计算公式,统一了0.3H简化破裂面和朗肯破裂面形式下的承载力计算公式。

| Abstract: | Based on the prototype preservation and numerical analysis of a reinforced gabion retaining wall,the failure surfaces adopted by different design manuals are compared and analyzed and the improved double line simplified failure surface model is proposed for reinforced earth retaining wall with double-twisted hexagonal steel wire mesh.After analyzed the results obtain by a field test done in a reinforced gabion retaining wall,the advantages of improved double line simplified failure surface model were analyz... |
