| 摘 要： | 本文用确定性和随机概率的方法研究了工桥墩台和小跨拱桥在恒载及活载（包括地震效应）作用下决定某截面上的偏心距，以便使其在设计规范规定的限度时所能通过的活载最大等级是什么，由于地震随机性强烈，故基于概率理论的结构可靠性方法优于确定性的方法，但在本文中的结果显示，这两种方法的最终结果十分接近。

| Abstract: | In this study, we discuss both the deterministic and the probabilistic methods to determine the eccentricity in cross section of masonry pier,abutment or arch bridge with small span under action of dead as well as live load (including seismic effect) whether it is within the defined limit.Due to the random behavior of earthquake motion, structure safety method based on probabilistic analysis suits better than deterministic method, yet our calculated results show that these two approaches coincide well to each other. |
