摘要
针对京珠高速公路信九段高边坡软弱破碎岩石出现的开裂情况,采用条块倾倒力学模型分析边坡稳定,找出最危险条块,用预应力锚索进行治理,提高岩体自稳能力和承载力,保证工程整体稳定性。简介加固前后的计算过程,介绍进行质量控制的实际施工方法以及施工工艺,以供借鉴。
To counter the fractures that the high slopes and weak rocks appear in Beijing-Zhuhai Expressway,the stability of slopes is analyzed by means of a mechanics model of stick-toppling, from which the most dangerous sticks are found. Those are administrated with prestressed anchor rope to improve rock body steady ability and bearing capacity,and to guarantee the whole stability of the project. Calculation procession before and after strengthening, the actual construction method of controlling the quality and construction technology are introduced, it is to give some help for researcher in this field.
