| Popis: | The article presents a model of the deformation of a reinforced concrete pile, which is subjected to the joint action of the load and chloride corrosion. The model takes into account the probabilistic nature of corrosion processes, the variation of the geometric and strength characteristics of the pile, the probabilistic nature of the load. A method for calculating the strength and durability of the pile, which takes into account the stages of the process of interaction of the pile with chlorides, is given, a calculation analysis is performed. The influence of various parameters on the durability of reinforced concrete piles is analyzed. A correlation dependence of pile durability on compressive load and a durability histogram are constructed. It has been established that the lifetime of a pile with a 95% security is 16 years, with a security of 70% - 52 years, with a security of 50% - 80 years. |
