在公路高边坡预应力的施工过程中,随着预应力施工技术的不断发展和进步,在预应力施工技术应用过程中,其施工工序也越来越完善。在施工过程中,采用预应力锚索施工技术能够达到对公路的高效防护,保证公路的良好运行和安全使用,提高公路的使用寿命,降低安全事故的发生率,在公路高边坡施工过程中得到了广泛的发展和应用。预应力锚索防护技术主要是通过水泥砂浆在有效深度的锚孔底端与周边完整的岩层形成锚固体,锚固体与孔壁之问就会形成摩擦力,提供一个反作用力,在锚索的预应力下,利用框架岩坡面最后将主动应力传递给稳定岩层,达到加固的效果。高边坡预应力锚索技术是确保高边坡稳定的重要施工工艺,直接关系着高速公路的使用安全,在高边坡施工中应该得到重视。
During the construction of prestressed highway high slope, with the continuous development and advancement of prestressed construction technology, the construction process of prestressed construction technology is also more and more perfect. In the construction process, the use of prestressed anchor cable construction technology to achieve efficient protection of the highway to ensure the good operation and safe use of roads to improve the service life of the road and reduce the incidence of accidents, high-slope in the highway construction process Has been widely developed and applied. Prestressed anchor cable protection technology is mainly through the cement mortar in the effective depth of the bottom of the anchor hole and the integrity of the formation of rock formation around the anchor, the anchor and the hole wall to ask the friction will be formed to provide a reaction force in the cable Under prestress, the active stress is finally transferred to the stable rock by the slope of the framework rock to achieve the reinforcement effect. The prestressed anchor cable technology of high slope is an important construction technology to ensure the stability of high slope. It is directly related to the safety of the expressway and should be taken seriously in the construction of high slope.
