岩土预应力锚固技术研究现状及发展趋势分析

    Research status and development trend analysis of geotechnical pre-stressed anchoring technology

    • 摘要: 通过回顾国内外岩土预应力锚固的发展历史,总结了预应力锚固技术在相关基础理论、规范设计、预应力问题研究等方面取得的最新进展,系统分析了预应力锚固技术在锚固效应与荷载传力机理、应力腐蚀与防护、锚固材料与施工工具、预应力损失机理、灌浆材料的胶结强度、群锚效应的影响以及现有检测水平不足方面的现状和问题,同时针对现阶段岩土预应力锚固的各种理论和技术试验远不能满足实际工程这一现象,提出了基于现代信息化和大数据等理论方法并据此对今后未来发展方向进行分析和展望,期望能为该领域发展提供参考价值。

       

      Abstract: By reviewing the development history of geotechnical prestressed anchoring at home and abroad, the latest progress of prestressed anchoring technology in related basic theories, standard design, prestressing problems research and other aspects is summarized, and the anchoring effect and load of prestressed anchoring technology, force transmission mechanism, stress corrosion and protection, anchoring materials and construction tools, pre-stress loss mechanism, cementing strength of grouting materials, influence of group anchoring effect, and current status and problems of insufficient detection level, are systematically analyzed. At the same time, aiming at the current stage problems of geotechnical pre-stress, various theories and technical tests of stress anchoring are far from satisfying the phenomenon of actual engineering. The theoretical methods based on modern informatization and big data are proposed, and the future development direction is analyzed and prospected accordingly. It is hoped that they can provide reference value for the development of this field.
