摘要
为探求实际大直径圆筒结构码头真正的受力状态,开展了大直径圆筒结构码头原型观测研究,即直接观测研究大直径圆筒码头使用时结构的受力状态。大直径圆筒结构码头原型观测所获得的现场数据由于包含有附加的、干扰的信息而和实验室所获得的数据具有不同的属性,因此不能直接用于判断和分析结构的受力状态。正确的做法应在分析前对数据进行处理,处理的方法包括评价数据可靠性、分离水压力、确定数据初值、剔除异常值、回归分析等。
To explore the stress state of the large-diameter cylinder wharf, this paper conducts the prototype observation, i.e. observing and studying directly the stress state of the wharf structure during operation. Since the site observation data from the prototype observation are different from those obtained from the laboratory in the attribute due to the additional interference information, it can not be used directly to judge and analyze the stress state of the structure. The data shall be processed before they are used for analyzing, including evaluating the data reliability, separating the water pressure, determining the initial data, excluding the outliers, and making regression analysis, etc.
