摘要:

在采用透水扭工字块体防护桥墩局部冲刷的措施中, 由于扭工字块体自身的透水能力允许部分水流穿越防

护体系, 构成扭工字块体的杆件对水流产生干扰作用, 消耗水流的紊动能量, 有效削减了行近水流的流速

。透水扭工字块体防护体系内部的近底流速小于河床泥沙的起动流速, 这保证了河床床面泥沙不被冲走,

还能使上游水流带来的泥沙部分落淤在防护体系内部。相对于传统的抛石防护方式, 透水扭工字块体防护

方式采用的扭工字块体重量较大、重心较低、结构稳定性较好, 不会因水流冲积而翻滚、流失, 非常适用

于桥梁水下基础的冲刷防护。

Abstract:

In the measures of partial scouring of piers with permeable dolosses, the permeable function

of the dolosses allows some of the water to flow through the protection system, through which

the members of the dolosses interfere with the water flow, the turbulence of the water flow

is consumed, and proximate flow rate is effectively reduced.The near-bottom flow velocity

inside the permeable dolosse protection system is smaller than that of the river bed

sediment, which ensures that the sediment on the river bed is not washed away, and the

sediment caused by the upstream water flow is deposited in the protection system.Compared

with traditional riprap protection method, the permeable dolosse protection system has a

large weight, a low center of gravity, and a favorable structural stability, which does not

tumble and lose due to water flow alluvial, which is very suitable for scour protection for

underwater foundation of bridges.
