| 1 | Design of Distorted Wave Protection Armor Units显示文摘In consideration of the global optimization for engineering projects, a group of calculation formulas have been derived by means of theoretical derivation and model tests. On this basis, a design procedure for the distorted units is proposed, by means of which the distorted units of an anology shape and an identical porosity ratio with the original units can be obtained after conducting a distorted enlargement and a normal contraction. The stability waveheight and stability factor of the distorted unit can be calculated with the enlargement factor, a, of the horizontal dimension of the distorted unit, or with the contraction scale, A , of the contracted distorted unit. As a result, the stability of the armor unit can be significantly improved without increasing the quantity of concrete. For the same wave met by the original units, the thickness of placement of the contracted distorted unit can be obviously reduced, thus, a large quantity of concrete can be saved, consequently, economic benefit can be achieved. | Lou Hongen Senior Engineer, Nanjing Hydraulic Research Institute, 210029, Nanjing | 1992 | China Ocean Engineering1992，7，4： | 0 |
| 2 | MULTI-DIRECTIONAL WAVE SUPERPOSITION OF WAVE DIFFRACTION显示文摘Characteristics of the natural wave cannot be successfully described by only using wave frequency spectra. In laboratory, natural wave conditions cannot be simulated exactly by harbour sheltering experiment with irregular long-crested waves, especially the results of diffraction tests with reflection source are often far away from the reality. So directional wave spectrum must be introduced to experiment on wave diffraction, except for one directional swell.At present, only a small number of laboratories in the world have possessed directional spectrum wave producer because of its complication and expension. This paper describes the experiment for multi-directional wave superposition of wave diffraction, with the conventional regular wave producer and one-direction irregular wave producer. The test results are of equal value with that from directional spectra wave. This method is suitable for rational design of harbour engineering projects and can be adopted in future practice. | Lou, Hongen Wang, Yongjun Su, Weidong Wang, Hong | 1989 | China Ocean Engineering1989，4，2： | 0 |
