现代气压沉箱工法在深水桥梁基础中应用探讨

Application of Modern Pneumatic Caisson Method in Deep-water Bridge Foundation

通过对各种深水桥梁基础形式的比较,气压沉箱基础在施工质量、抗震性能等方面有着独特的优势。文章介绍了采用现代气压沉箱技术进行深水桥梁基础施工的主要流程,并初步探讨了该工法在实际应用中的技术难点,对其中的关键施工技术进行了详细分析,并提出相应的施工对策。最后通过一个国外工程实例介绍了气压沉箱工法在深水桥梁基础中的应用情况及效果,希望能为我国深水桥梁基础施工方案的选择提供参考。

Through the comparison of several types of deep - water foundations for bridges, the modem pneumatic caisson method was highlighted due to its unique advantages. This paper introduced the construction sequence of deep -water bridge foundations with modem pneumatic caisson, and discussed some critical construction techniques. Based on the analysis, some construction measures were also presented. Finally, combined with one construction example in Japan, the application of the modem pneumatic caisson method and its effects were illustrated. It will offer references for the determination of deep - water bridge foundation type in China.
