岩质高边坡防治是一项复杂的系统工程,有效可靠的岩土锚固设计,对于工程建设具有十分重要的现实意义。以大连某高边坡为研究实例,探讨破碎岩质边坡加固的有效措施,充分从边坡工程地质条件出发,论证了压力分散型预应力锚索锚固体系对破碎岩质高边坡防治设计的适宜性与可靠性,并以对比研究的方法系统地分析了压力分散型预应力锚索的受力机制及其优越之处。
Prevention and control of rocky high slope is a complicated systematic project. The effective and reliable design of rock and soil anchorage has very important practical significance for engineering construction. Taking a high slope in Dalian as an example, the effective measures to reinforce the broken rock slopes are discussed. Based on the engineering geological conditions of the slopes, it is demonstrated that the pressure-dispersion type prestressed anchor cable anchoring system is effective for the prevention and control of high broken rock slopes The suitability and reliability of the stress-relief prestressed anchor cable were systematically analyzed by comparative method.
