Abstract:
An index system of steel deck pavement design is proposed according to the study and classification of failure types. Furthermore the axle-equivalent equation is presented according to the fatigue principle of pavement structures. Based on indoor experiments and theoretical analysis, this paper studies the stress characteristics of three different axle types which are corresponding with the other three typical pavement structures, and also presents the parameters of each axle’s equivalent formula. The three axle types include single-axle single-wheel, single-axle double-wheel and double-axle double-wheel. According to analyses of influential factors such as climate, environment, traffic and stress condition, the developed axle equivalent formula and the parameters modified by the field test data can be applied in the design of a new bridge deck pavement and the assessment of an existing bridge deck pavement.
通过对钢桥面铺装主要病害的研究与分类, 提出了桥面铺装结构设计的指标参数体系, 并应用疲劳等效的原理, 推导了轴载等效换算公式.根据室内试验和理论分析, 分别研究了3种典型的铺装结构对应3种不同轴载类型的受力特性, 并提出了各自轴载换算公式的参数的取值.3种轴载类型包括:单轴单轮组、单轴双轮组、双轴双轮组.通过对桥面铺装的影响因素包括气候与环境、交通、受力状态等使用条件的分析, 提出的轴载等效换算公式与参数取值经过现场测试数据进行修正后, 可以应用于新建桥梁桥面铺装的设计和已建桥梁桥面铺装使用状况的评价.
