摘要
本研究借助河工模型试验手段,通过对沉井在不同的入水深度时沉井底部垂线流速分布情况的观测,探讨了沉井下沉过程的局部冲刷发展的原因,本研究对制定沉井施工工序和掌握恰当时机进行沉井具有指导意义。
The paper discusses the cause of part scouring in the process of open caisson subsidence with hydraulic model test according to observation of vertical flow velocity distribution for bottom of oper caisson.This study has the guiding meaning for the open caisson.
