预应力锚索对破裂破碎软质砂泥岩高边坡加固的应用

软弱岩石的边坡支护一直是岩土工程中较为棘手的问题，尤其是受地质构造破坏形成的破裂破碎软弱岩体的边坡支护问题更为复杂。我国近十几年来，预应力锚索加固技术已广泛应用于建筑结构物加固、边坡治理、大型地下洞室及深基坑支护等工程。本文就受地质构造破坏的破裂破碎软弱岩体加固的工程实例，应用原位测试技术和经验反算确定设计参数和计算模型，应用多种成孔措施，有效的对大型复杂破裂破碎软弱岩体Ⅰ级高边坡采用预应力锚索加固技术加固边坡进行了论述。

Applying Prestress Anchor Cable to Reinforce the High Slope of Fractured Weak Rock

To reinforce slope of weak rock has been tough problem during rock soil engineering, especially for sl-ope consisting of broken weak rock. In our country near more than 10 years, the prestress anchor cable technique has been extensive applied in building, slope retaining and grotto. In this paper, based on example in engineering reinforce fractured weak rock,the home position test technique and the experience are applied to establish design parameters and models, adjust measures to suit local conditions, use prestress anchor cable to reinforce the high slope in fractured weak rock.
