摘要
以汉江孤山水利枢纽首级施工控制网的优化设计为例,提出了一种基于观测值内部可靠性指标的工程控制网优化设计方法。该方法在本质上属于模拟法,但增加可靠性指标后,具有量化的优化设计准则,不以人的知识和经验为转移,优化结果既具有一致性,也不失严密性。此方法对类似工程项目具有借鉴意义。
An optimum design method for engineering control network based on reliability indices of observations was proposed in this paper, taking first construction control network in the Gushan water conservancy project on the Han River for example. This method is a simulation method in nature, yields quantized optimum design criteria after adding reliability indices, and is independent of man's knowledge and experience. The optimized results have consistency, and without losing strictness.
