| 中文摘要: |
| 结合《板桩码头设计与施工规范》(JTJ292-98)修订的需要，研究了影响板桩结构各项计算内容的主要因素，将计算板桩结构的参数作为随机变量，对其统计特性进行了分析，提出了板桩结构的可靠度分析方法。对国内14个板桩结构的可靠指标进行了计算，结果表明，板桩结构各项计算内容的可靠指标均有所差别，其中，拉杆抗拉强度可靠指标最高，其次是板桩墙抗弯强度，锚碇结构稳定性和“踢脚”稳定性。 |
| 英文摘要: |
| In order to revise Code for Design and Construction for Quay Wall of Sheet Pile (JTJ292 98), the main factors influencing the calculated results are discussed. The parameters involved in the structure calculation of sheet pile are regarded as stochastic variables, which are statistically processed. A method for reliability analysis proposed in this paper is applied to the computation of reliabili
ty of 14 sheet pile structures in China. The results show that the indexes of reliability are different for different parts. The index of reliability of the tensile strength of tie rod is the highest, the next is the bending resistant strength of the steel pile wall, and the lowest are those for the anchoring structure and tie rod setting point. |
