桥墩桩基冲刷病害加固设计研究

Study of strengthening design for damage of bridges pier by river scour

近年来洪灾频发,由于自然及人为原因,河床掏刷现象较严重。随着河床覆盖层显著降低,导致桥墩刚度、桩基承载力不足和保护层脱落等病害。以某大桥为例,对桥梁桩基冲刷病害的加固维修技术进行探讨。

Because of frequent floods in recent years,serious scour of river bed has been occurred by natural and anthropogenic causes.With the river bed cover layers has been significantly reduced,serious damage to the rigid of pile,bearing capacity of pile and concrete cover has been occurred.With a bridge on expressway for example,the strengthening of existing pile has been discussed to damage of bridge pile by the scour of river.
