Characteristic data have been worked out, including the maximum Lyapunov index λ, fractional dimension D, lacunarity Λ and eight energies of various frequency bands. After being normalized, they can function as the characteristic vectors. Then, they are transmitted into an artificial neural network to perform pattern recognition.Starting from the mechanism of ultrasonic generating, initial ultrasonic pulses are calibrated. A stylish discharge source is directly coupled with the ultrasonic sensors, and work out actual discharge magnitude.

On the basis of making it clear that laterization includes such three integrated stages as weathering, micro-granularity and soil formation of laterite, the thesis illuminates characteristics of Kunming laterite in chemical composition, physical mechanics, composition of granules, fractal dimension of granularity and the connection of granules. The experiment using soil reinforced agent to solidify the laterite shows that the mechanical traits of laterite have been improved because of its involvement, the best compact indicators and shear strength ones increased and the indicators of laterites penetrability and compression decreased. The effects of reinforcement can be weighed through its coefficient and the mechanism of reinforcement can find the explanation in the effect of soil reinforced agent on the laterite granules, the changes in the electric double layer caused by soil reinforced agent and its enwrapping of laterite granules.
