Single safety coefficient method is still the design criterion of sluice engineering structure presently, but will not present reliability of sluice in a quantitative and scientific way.
The shear reliabilityof columns are analyzed , the reliability index under different shear strengthen coefficient are obtained.
此外，分析了柱的抗剪可靠度，得出了不同剪切增强系数下柱的抗剪可靠指标。

The reliabilityof simple correlation coefficient is lower because of the cross correlation of agronomic character indices, and the reliabilityof partial correlation coefficient is higher.
