“…The cause of this instability derives from the constantly changing underground environment. In 1928, Logan determined that the degradation of a buried material is strongly dependent on the characteristics of the soil in which it is buried [42]. Most of the destructive processes that affect buried metals are of an electrochemical nature, mainly associated with the characteristics of the soils in which they are located [43,44].…”

Around the world, there are thousands of metal structures completely or partially buried in the soil. The main concern in their design is corrosion. Corrosion is a mechanism that degrades materials and causes structural failures in infrastructures, which can lead to severe effects on the environment and have direct impact on the population health. In addition, corrosion is extremely complex in the underground environment due to the variability of the local conditions. The problem is that there are many methods to its evaluation but none have been clearly established. In order to ensure the useful life of such structures, engineers usually consider an excess thickness that increases the economic cost of manufacturing and does not satisfy the principles of efficiency in the use of resources. In this paper, an extended revision of the existing methods to evaluate corrosion is carried out to optimize the design of buried steel structures according to their service life. Thus, they are classified into two categories depending on the information they provide: qualitative and quantitative methods. As a result, it is concluded that the most exhaustive methodologies for estimating soil corrosion are quantitative methods fed by non-electrochemical data based on experimental studies that measure the mass loss of structures.

“…The objective of the algorithm is to approximate an unknown function f that represents the relationship between the soil variables that influence corrosion and the loss of thickness that will occur in the steel. To do this, MARS searches for the approximation function f by creating subregions (nodes) and carrying out linear combinations of sets of base functions B i parameterized by the position of said nodes (4).…”

“…The underground environment is characterized by great corrosive complexity [2,3]. The cause of this instability is the fact that the soil is constantly changing and presents great variability in its local conditions [4,5]. Two geographically close soils may have different characteristics and, therefore, degrade steel with different aggressiveness.…”

Corrosion is the main mechanism of the degradation of steel structures buried in the soil. Due to its aggressiveness, the material gradually loses thickness until the structure fails, which may cause serious environmental problems. The lack of a clearly established method in the design leads to the need for conservative excess thicknesses to ensure their useful life. This implies inefficient use of steel and an increase in the cost of the structure. In this paper, four quantitative and multivariate models were created to predict the loss of buried steel as a function of time. We developed a basic model, as well as a physical and an electrochemical one, based on multivariate adaptive regression spline (MARS), and a simpler model for comparative purposes based on clusters with Euclidean distance. The modeling was synthesized in a computer tool where the inputs were the characteristics of the soil and the time and the outputs were the loss of thickness of each predictive model and the description of the most similar real tests. The results showed that in all models, for relative errors of 10%, over 90% of predictions were correct. In addition, a real example of the operation of the tool was defined, where it was found that the estimates of the models allow the necessary optimization of steel to fulfill its useful life.
