    摘要:

    自从对锚索类型按内锚固段受力状态科学地分为:拉力型、压力型、荷载分散型;荷载分散型又分为:拉力分散、压力分散、拉压分散型以来,引起岩土锚固工程界技术人员的极大关注,并广泛采用荷载分散型锚索对高速公路边坡、路基以及深基坑支护等复杂地基的加固工程中取得了可喜的成果。当然,对于承载力高的岩体边坡、坝基、洞室加固及抗浮工程,对各种构造物的锚固工程中荷载分散型锚索也不能不说是最佳的选择。本文介绍近年来大量采用荷载分散型锚索结构取代以往常用的拉力型锚索的工程实例,特别是通过对压力分散型锚索与拉力型锚索受力状态的分析比较以及各种功能的优势,肯定其结构的合理性、良好的防护措施、可靠的锚固效果以及方便的工艺,经济的造价,说明新型锚索结构取代拉力型锚索的必然性,这无疑将是岩土锚固界的一场技术革命

    Abstract:

    Since the type of anchor cable according to the anchoring section of the force state scientifically divided into: tension type, pressure type, load dispersion type; load dispersion type is divided into: tension dispersion, pressure dispersion, tension and pressure dispersion type, caused great concern of geotechnical anchoring engineering technical personnel, and widely used load dispersion type of anchors on highway slopes, road beds, as well as deep pit support and other complex foundations of the reinforcement project has achieved promising results. Of course, for the bearing capacity of the anchor cable, the load dispersing anchor cable can be used. Of course, for the high bearing capacity of the rock body slope, dam foundation, cave reinforcement and anti-floating project, the anchorage of various structures in the load dispersing anchor cable can not be said to be the best choice. This paper introduces in recent years a large number of load dispersing anchor cable structure to replace the previous commonly used tension type anchor cable project examples, especially through the pressure dispersing anchor cable and tension type anchor cable analysis and comparison of the state of force and a variety of functional advantages, sure that its structural reasonableness, good protective measures, reliable anchoring effect and convenient technology, economic cost, indicating that the new anchor cable structure to replace the tension type anchor cable This will undoubtedly be a technological revolution in the field of geotechnical anchoring.
