应用结构可靠度理论，对给出的一种小型空心砌块挡土墙最优断面进行可靠指标计算。计算中考虑了墙底土层粘结力的影响及变量间的相关关系，应用变量相关时的ＪＣ法程序求得可靠指标。计算表明该砌块挡土墙断面基本上能满足可靠性要求，若用此断面进行设计并适当采取抗倾、抗滑措施，即可使砌块挡土墙这种新型结构推广使用于水利、水电、道桥等工程中
Applying structural reliability theory, the reliable index calculation of the optimal section of a small-sized hollow block retaining wall is given. In the calculation, the influence of the adhesive force of the soil layer under the wall and the correlation between the variables are taken into account. The reliability index is obtained by applying the JC method when the variables are relevant. The calculation shows that the section of the retaining wall of the block can basically meet the reliability requirements. If this section is used for design and appropriate anti-dip and anti-slip measures are taken, the new structure of the block retaining wall can be used for water conservancy, In hydropower, bridges and other projects
