瓯飞一期围垦工程东堤镇压层块石护面结构稳定性试验研究

Experimental Research on Stability of Armour Rock Structure in East Dike Repressive Layer of Oufei Reclamation Project

为了避免理砌块石护面发生跳脱、翻滚、位移等失稳现象,以及解决瓯飞围垦工程料源紧缺的现实问题,开展了波浪作用下迎潮面镇压层理砌块石、砼半灌块石护面结构稳定性的室内模型及现场对比试验。试验结果表明,砼半灌块石护面结构在满足工程设防标准的前提下,能够有效降低块石重量及护面厚度,提高料源的利用率及块石护面结构的抗风浪能力。

Armour rock structure often appears instability like escape,rolling,displacement.Oufei reclamation project had the problem of rock material shortage.The stability of different revetment structure under the action of wave were analyzed by laboratory test and field test.It shows that on the premise of satisfying defending standards of project,concrete half-grouting armour rock can effectively reduce rock weight and armour thickness,and improve the utilization of rock material and wave attenuation performance of armour structure.
