南京长江三桥南塔钢套箱受水流力作用的试验研究

Test Study of Water Current Forces on Boxed Steel Cofferdam for South Pylon of the 3rd Nanjing Changjiang River Bridge

介绍南京长江三桥主桥钢套箱水流力试验的方法及结果,对试验得出的数据进行了分析,对"哑铃型"钢套箱所受的横向水流力和纵向水流力的系数的规律进行了分析比较。

The test methods and results of water current forces on the boxed steel cofferdam for the south pylon foundation of the 3rd Nanjing Changjiang River Bridge are presented. The data obtained from the tests are studied, and the regularities of coefficients of the transverse and longitudinal water current forces on the dumbbell-shape cofferdam are analyzed and compared as well.
