可靠性原理在淤地坝设计与评价中的应用

Application of the Reliability Principle in the Design and Evaluation Practice of Silt Storage Dam

淤地坝建设对改善黄土高原生态环境,减少黄土高原水土流失意义重大。运用可靠性原理对淤地坝设计、工程安全性强制规范、风险概率控制测评等3项指标用相应的数学公式进行计算,得出淤地坝类工程从设计到施工、测评方面在数量上的参数指标,对提高淤地坝的设计效率和设计精度以及减少设计审查过程中的主观盲目性,提供了有益的借鉴。

The construction of the silt storage dam is of great importance to the improvement of the loess plateau ecosystem and to the reduction of the soil erosion. According to the reliability principle in the applied mathematics in this paper, the corresponding mathematical formulae were used to calculate three groups of indexes, the dam design, the compulsory norm for engineering safety and the control and assessment of the risk probability after testing and examination of the silt storage dam. The quantitative parameters and indexes calculated for the design, construction, measuring and evaluation of the silt storage dam engineering provided beneficial references for the decrease of the subjective blindness and the increase of the efficiency and accuracy for the design and inspection of the particularly for the reliability of the engineering.
