摘　　要：研究以调水工程河道断面优化为背景,提出基于边坡可靠性分析的设计方法。通过建立边坡开挖模型,采用随机场理论,分析土体参数变化,确保每一级挖掘后边坡安全系数满足工程设计要求。结果表明,优化后的断面水位更为稳定,水流速度波动范围减小,验证了该方法的有效性。研究有助于确保河道断面在挖掘过程中的稳定性,从而提高工程的可行性,对调水工程领域与河道断面优化设计中具有重要意义。A design method based on slope reliability analysis is proposed based on the background of river section optimization of water diversion project.By establishing the slope excavation model and using the random field theory to analyze the variation of soil parameters,the safety factor of slope after excavation can meet the engineering design requirements.An example shows that the optimized section water level is more stable and the fluctuation range of water flow velocity is reduced,which verifies the effectiveness of the method.The study is helpful to ensure the stability of river section in the excavation process,so as to improve the feasibility of the project,which is of great significance in the field of water transfer engineering and the optimization design of river section.
