Bridge Type Selection of Key Technology Research Based on Adaptive

Conduct bridge type adaptability research in national scope, based on this, construct the highway bridge type adaptability database system [1], and put forward the bridge type adaptability evaluation method, evaluation index and its value based on the typical bridge comprehensive performance. On the foundation of the database system and bridge adaptability index, establish the bridge type selection analysis model based on the analytic hierarchy process and fuzzy mathematics theory, then depend on this, conduct comparison and selection analysis on the new bridge type sample and form the bridge type selection key technology [2].
