桥梁的技术经济比较是一项非常复杂的工作,这是因为其影响因素极多,而这些因素又要依靠当地乃至全国的建设条件而定。属于当地条件的有:工程地质、水文、建筑施工机构以及通航、规划、建筑等条件和其他要求。同时也与全国的基本条件,诸如劳动力和材料价格情况、对于大规模建造桥梁结构的工业化基础是否具备等有关。通常在技术设计阶段完成之后,即可确定被采用的桥型方案的效果。首先应从工程造价与包括维修和经常养护的项目在内的
The technical and economic comparison of bridges is a very complicated task because of the many factors that affect it, and these factors depend on the local and even nationwide construction conditions. Belong to the local conditions are: engineering geology, hydrology, construction and construction agencies and navigation, planning, construction and other conditions and other requirements. At the same time, it is also related to the basic conditions in the country, such as the labor force and material prices, and the availability of the industrialized foundation for large-scale construction of bridge structures. After the technical design phase is completed, it is usually possible to determine the effect of the bridge scheme being adopted. First of all should be from the project cost and including maintenance and regular maintenance projects included
