Method for evaluating health indexes of harbor concrete member based on analytic hierarchy process

Abstract

The invention provides a method for evaluating the health indexes of a harbor concrete member based on the analytic hierarchy process. The method for evaluating the health indexes of a harbor concrete member based on the analytic hierarchy process comprises the following steps: confirming the target layer, the criterion layer and the decision layer and structuring a judgment matrix; calculating the weight coefficients of the six variables of the criterion layer assigned on the basis of the target layer; and calculating the score of the target layer according to the consistency weight distribution equation to measure the health status of concrete. By means of the analytic hierarchy process provided by the invention to evaluate the health indexes of a harbor concrete member, the working performances of the harbor concrete members can be monitored accurately, and the defects that the calculation amount is large, the calculation time is long and the calculation is difficult to use in routine conditions in the evaluation of concrete health indexes in engineering practice can be solved effectively, and the method for evaluating the health indexes of a harbor concrete member based on the analytic hierarchy process has the advantages of less unknown quantity, small calculation scale, high accuracy and convenient application.

Description

technical field [0001] The invention relates to a method for evaluating the health index of a concrete component of a seaport, in particular to a method for evaluating the health index of a concrete component of a seaport based on an analytic hierarchy process. Background technique [0002] The density, width, depth, and tortuosity of concrete components deep in seawater are affected by the erosion of various salt ions such as chloride ions in seawater, resulting in cracks, spalling, and even damage to their compactness. Therefore, in the field of construction, judging and controlling the service life of concrete components under seawater corrosion to reduce their deterioration and damage has become an important task at present. [0003] At present, the focus of research on the durability of concrete structures in this field is to quantitatively analyze the influence of chloride ion diffusion in concrete components on the thickness of concrete cover, age attenuation, etc. Th...
