在对削角直立式防波堤研究的基础上,第一次开展了削角圆筒防波堤的波压力试验。试验是在64×0.8×1.8米~3水槽内进行的,规则生波机的周期变化范围为0.6～2.4秒,波高变化范围为10～30厘米。测压工具为我所自制的电感式测压盒,自振频率900～1200赫芝,精度可测出1厘米水柱压力,有良好的稳定性、防水性和线性特征。沿圆筒对称直径剖开的标准断面见图1。
On the basis of the research on the vertical breakwater with chamfered corners, the wave pressure test of the chamfered cylindrical breakwater is carried out for the first time. The test was carried out in a 64 × 0.8 × 1.8 m ~ 3 tank. The regular wave generator had a period variation of 0.6-2.4 s and a wave height variation of 10-30 cm. Pressure-measuring tool for my self-made inductive pressure-measuring box, self-vibration frequency of 900 to 1200 Hertz, the accuracy can be measured 1 cm water column pressure, good stability, water resistance and linear features. The standard cross-section taken along the symmetrical diameter of the cylinder is shown in Figure 1.
