高边坡锚固工程中相关设计参数的选取,如锚固区域、锚索吨位、锚固角、锚索间距等将直接影响边坡加固的可靠性和经济上的合理性。以往的研究在预应力锚索锚固机理和锚固角优化等方面取得了较大的进展,但在高边坡锚固方案优化分析时较少综合考虑上述这些因素的影响。基于此,采用极限平衡和有限元相结合的方法,对某坝肩开挖高边坡的锚固方案进行了综合的优化计算分析,得到了优化的锚固方案。研究成果对于保证坝肩开挖高边坡的整体稳定,节约工程材料,降低施工成本具有重要意义,也可以供类似工程参考。
The selection of relevant design parameters in high slope anchoring project, such as anchorage area, anchor cable tonnage, anchorage angle and cable spacing will directly affect the reliability and economic rationality of slope reinforcement. In the past, great progress has been made in the research on the anchoring mechanism and anchoring angle optimization of prestressed cables. However, the influence of these factors mentioned above is seldom considered in the optimization analysis of high slope anchoring solutions. Based on this, the method of limit equilibrium and finite element method is used to optimize and analyze the anchoring scheme of high side slope of a dam abutment, and the optimized anchoring scheme is obtained. The research results are of great significance to ensure the overall stability of the high side slope of excavated dam, save engineering materials and reduce the construction cost, and also can be used for reference for similar projects.
