发布时间：2018-10-29 14:38
【摘要】：顺水流沉排方式能有效减少水流对软体护底排的冲刷破坏,但由于在深水条件下顺水流沉排时受力情况复杂,施工过程中难以保证软体排结构的安全。对深水顺水沉放条件下软体排受力进行理论分析,并对理论计算结果进行现场试验验证。在受力分析的基础上提出了适合在深水顺水流沉放条件下软体护底排的结构设计方法,并在长江中下游航道整治工程中得到了较好的应用。
[Abstract]:The downflow drainage can effectively reduce the erosion damage caused by the flow under the soft bottom protection, but it is difficult to ensure the safety of the soft drain during construction because of the complexity of the forces acting on it in the deep water. The stress of soft discharge under the condition of deep water sinking is theoretically analyzed, and the theoretical calculation results are verified by field test. On the basis of stress analysis, the structural design method of soft bottom protection is put forward under the condition of deep water flowing and sinking, and it has been well applied in the regulation project of the middle and lower reaches of the Yangtze River.
