Considering the corrosion degree of reinforcement, the chloride penetration resistance of concrete and chloride concentration distribution in concrete, a health evaluation method for durability of harbor engineering was established by analytic hierarchy process (AHP). Analysis of a harbor in South China demonstrates that the health indicator for durability condition of existing structures can be effectively used to quantitatively health evaluation for durability of practical engineering.

The idea of diesel engine health evaluation is put forward, and the calculation flow, fast algorithm, and influencing factors of wavelet fractal dimension are analyzed. Through the real vehicle experiment, the corresponding relationship between the fractal dimension of the wavelet and the health condition of the diesel engine is calculated and analyzed. Three quantitative expression parameters, age health degree, dimension health degree, and comprehensive health degree, are defined considering the age and working condition of diesel engine. Finally, the consistency of health degree with vibration intensity, acceleration time, deceleration time, and fuel consumption was confirmed. It has been proved that it is feasible to evaluate the health of diesel engine with health degree.
