当前我国经济发展的主要运输方式为公路运输,公路运输的质量对我国经济发展起着至关重要的作用。公路与桥梁的连接处是整个公路施工过程的重点,其施工技术优劣、质量的高低直接影响到工程投入使用后,桥头“跳车”现象的发生频率。对于跳车现象的防治,要从设计着手,在进行施工前要针对施工方案及施工规划,以提高路基强度、耐久性和安全系数。
At present, the main mode of transport for China’s economic development is road transport. The quality of road transport plays a crucial role in the economic development of our country. The connecting point of highway and bridge is the key point of the construction process of the whole highway. The quality of its construction technology has a direct impact on the frequency of occurrence of “bridge jumping” phenomenon after the project is put into use. For the prevention and control of the phenomenon of jumping from the design to proceed with construction before construction plans and construction plans to improve the subgrade strength, durability and safety factor.
