摘要:
针对土层锚杆应力分布的复杂性,进行室内模型试验,利用所得数据,绘制了拉力型锚杆和压力型锚杆杆体全长上的应变分布曲线、同列锚杆锚固段末端点以及坡面处的应变分布曲线。在所得曲线的基础上,对坡体中锚杆的应力分布特征以及变化规律进行了分析及讨论,从而对其工作性能和加固机理进行初步研究。介绍了锚杆上剪应力分布的理论解,并将试验结果与理论分析结果进行了对比,两者基本吻合,验证了本试验结果的合理性和可靠性。
Abstract:
In allusion to complexity of stress distribution within the anchor, an indoor model test on anchors in clay is performed. According to the test data, the strain curves for stretched anchors and pressure-type anchors are plotted and the strain curves for idem anchor on the end of anchorage segment and slope are also plotted. With focus on the stress transmission properties and its changing regulation for anchors in soils, the working performance and mechanisms of the anchor are studied. The authors give a theoretical solution for stress distribution within the anchor, and make a comparison between the theoretical result and the test result. The test result is in accordance with the theoretical analysis result, which validates the rationality and the reliability of the conclusion, thus providing a reference principle for design of anchor in projects.
