冻结法施工在润扬大桥南锚碇基础工程中的应用

Application of Congelation Method to Foundation Engineering of South Anchorage of Runyang Highway Bridge over Yangtze River

根据土层冻结工法的基本原理 ,结合润扬长江公路大桥工程实际 ,介绍了在润扬大桥南锚碇基础基坑开挖时 ,采用冻结工法加固土层进行基坑封水的原理和工程实践 ,并探索了冻结工法在桥梁工程施工中的应用前景。

In this paper the application of congelation method is presented in the construction of foundation engineering of highway bridge on the basis of basic theory of the congelation method.In contrast to traditional contruction methods and through practice of congelation method in the construction of Runyang Highway Bridge over Yangtse River, the congelation method is proved technically feasible and economically preferable.Meanwhie,the application foreground of the congelation method is discussed.
