跨海桥梁桩基基础所受的波流荷载是跨海桥梁设计中重点考虑的荷载之一,实际工程中波流力的计算多参考《港口与航道水文规范:JTS145—2015》中推荐的单桩桩基基础波流力计算方法,未合理考虑局部冲刷形状的影响。以港珠澳大桥为例,在桩基基础波流力和冲刷试验结果的基础上,通过对计算模型中流速、CD、CM等参数的选取进行修正,提出了考虑局部冲刷形状的桩基基础波流力计算方法,在保证工程安全性的同时兼顾了工程的经济性,并成功应用于港珠澳大桥桥梁桩基的设计中。 相似文献

The interaction between waves and porous breakwater has an important theoretical significance and great application value of engineering. In this paper, the tests of the core material’s influence in rubble mound breakwater on wave propagation are carried out. The relations among the transmitted wave height, incident wave element, and breakwater width are discussed. The calculation formula is obtained. The test results show that different core materials have obvious influence on wave propagation. 相似文献
