| 摘 要： | 通过横断面渗流土工试验,人工加压线源液化土体,观察到泥沙起动的过程和液化土体横断面的基本形态,发现线源渗透破坏服从最小阻力趋向原则。利用土体产生渗透破坏而深层起动泥沙的潜力,通过河道中泓取直深埋压力渗管,达到节水冲沙、稳定主槽、降槽防洪之目的。

| Abstract: | During the cross-sectional seepage flow soil test and line fountain liquefaction solum by artifical pressure,the process of sediment incipient motion and cross-sectional basic configuration of liquefaction solum have been observed.Meanwhile,the minimum drag tendency of line fountain deformation due to seepage also can be found.Fully making use of the capability that is deformative due to seepage of the solum,deeper layer sediment can be established.The compressive force leak canal can be buried vertically and deeply under the centre of river in order to flush sand and save water,stabilize main channel and reduce the depth of channel and prevent flood. |
