Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods face challenges in accurately determining the threshold of underground depth at which reinforced concrete structures buried in the ground are less prone to degradation, leading to insufficient accuracy in predicting their degradation.
Innovation Solution
A degradation predicting method that evaluates condensation occurrence conditions, calculates condensation time, determines a threshold of underground depth based on the relationship between condensation time and depth, and predicts degradation of reinforced concrete structures using these thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to predict degradation, then the prediction process is simple, but the prediction accuracy is insufficient
Solution Approach 1:
The prediction method is segmented into multiple distinct steps: condensation occurrence condition evaluation, condensation time calculation, threshold determination, and degradation prediction. Each step processes specific parameters independently, allowing complex calculations to be broken down into manageable components that improve accuracy without overwhelming complexity
Solution Approach 2:
The method performs preliminary evaluation of condensation occurrence conditions and calculates condensation time before final degradation prediction. By pre-calculating these intermediate parameters and establishing thresholds in advance, the method prepares accurate input data for the final prediction, thereby improving overall prediction accuracy
2Measurement precision
If the threshold of underground depth is not determined, then the prediction method is simple, but the degradation prediction accuracy is insufficient
Solution Approach 1:
The threshold of underground depth is determined in advance through preliminary analysis of condensation time data at different depths. This pre-established threshold is then used directly in the degradation prediction step, avoiding repeated calculations and reducing the time required during actual prediction operations
Solution Approach 2:
The method dynamically determines the threshold based on the calculated condensation time and its relationship with underground depth. Rather than using a fixed arbitrary value, the threshold adapts to the specific conditions of the reinforced concrete structure, improving prediction accuracy for varying depths
