非均匀土壤中阴极保护电位数值模拟计算

摘要

The soil resistance was applied to stand for the soil difference and the new mathematical model in heterogeneous soil was established. The boundary conditions take activation polarization and concentration polarization into account. Confirming the numerical simulation with cathodic protection simulation device proves the feasibility of employing this model to calculate cathodic protection potential.%利用土壤电阻率表征土壤的非均匀性,建立非均匀土壤中的阴极保护电位计算模型,边界条件考虑了活化极化和浓差极化的双重作用,通过室内阴极保护模拟装置验证了数值模拟计算结果,证明用该模型计算非均匀介质的阴极保护电位是可行的.
