长江上游水深,流急,河床多为深层砂卵石覆盖,下卧软质砂页岩互层,基岩强度不高,易风化。在这种河流上建桥,水中基础是关键。本文介绍了沪州长江大桥主孔二号墩基础的设计。设计采用高桩承台钻孔灌注桩基础。本工程已于81年完成,经全桥建成后的系列测试、检验,证明本设计是成功的。
In the upper reaches of the Yangtze River, water depths and currents are acute, and most of the riverbed is covered by deep sand and gravel. The interbedded soft sand shale lies below each other. The bedrock strength is not high and weathering is easy. Bridge in this river, the foundation in the water is the key. This article introduces the design of the foundation of No.2 Pier in Huzhou Changjiang River Bridge. Design using high-pile caps pile foundation. The project has been completed in 81 years, after the completion of the full bridge test series, testing, to prove that the design is successful.
