【摘要】：针对目前越浪量测量方法中存在的实际问题,提出了以一种液压传感器为测量工具、基于水箱内水深变化来计算越浪量的新方法——测深法。全面描述测深法的基本原理和从液压传感器提供的波动压力数据得到平均越浪量、单波越浪量和越浪比例所需的操作步骤和数据处理方法,并通过试验评估了该方法的试验精度。结果表明:测深法能够可靠地被应用于各种以越浪量测量为主要目的的模型试验,其中,平均越浪量的测量精度与传统方法相当,单波越浪量的相对误差普遍可控制在5%以内;相比于现有越浪量测量方法,测深法具有对单波越浪的信号识别能力强、适用范围广、试验操作简单、维护成本低、设备通用性好等优点。
[Abstract]:In view of the practical problems existing in the current wave-surpassing measurement methods, a new method called bathymetric method, which uses a hydraulic sensor as a measuring tool and based on the variation of water depth in the water tank, is proposed. The basic principle of the bathymetric method and the operation steps and data processing methods needed to obtain the average surpassing volume, the single wave overtaking quantity and the overshoot ratio from the wave pressure data provided by the hydraulic sensor are described comprehensively. The accuracy of the method is evaluated by experiments. The results show that the bathymetric method can be reliably applied to all kinds of model tests whose main purpose is to measure the surpassing quantity. The measurement accuracy of the average surpassing quantity is similar to that of the traditional method, and the relative error of the single wave surpassing quantity can be generally controlled within 5%. Compared with the existing measurement methods, the sounding method has the advantages of strong recognition ability, wide application range, simple test operation, low maintenance cost and good generality of equipment.
