基于压力膨胀型囊袋锚杆在公路高边坡应用的研究分析

Based on Research and Analysis on the Application of Pressure-expanded Bladder Bag Anchors in Roadside High Slopes

锚杆支护广泛的运用于工程技术的实际应用中,它不仅可以运用在煤矿巷道支护中,在边坡、隧道以及建筑抗浮工程中也有着广泛的应用。可通过锚杆杆体的纵向拉力作用,克服岩土体抗拉能力远远低于抗压能力的特点。基于压力膨胀型囊袋锚杆在广西上思至防城港高速公路高边坡的实际应用,研究和分析了压力膨胀型囊袋锚杆的各项性能,并对此锚杆的应用市场提出了推广前景。

Anchor support is widely used in engineering technology,not only in coal mine roadway support,but also in slope,tunnel and building floatation engineering.The longitudinal tension of the anchor rod can overcome the feature that the tensile capacity of the geotechnical body is much lower than the compressive capacity.Based on the practical application of pressure-expanding bag anchor in the high slope of the highway from Shangsi to Fangchenggang in Guangxi,researches and analyzes the properties of pressure-expanding bag anchor,and presents the promotion prospects of the application market of this anchor.
