<p>PROBLEM TO BE SOLVED: To create a database system for the information on digging faces in various tunnels in the whole country in data base to manage and retrieve the information efficiently. SOLUTION: A user accesses a system server 4 from a terminal unit 21 in a work place, inputs observation item data of the tunnel from a displayed input screen, and inputs facing observation data composed of evaluation of compression strength in facing, denaturing due to weathering, crack interval, crack condition, running inclination, amount of sump water, and deterioration due to water from the terminal unit 21 in the work place. The system server 4 calculates a facing evaluation point corresponding to the specifications of an arbitrary person who gives an order from the inputted data and stores and manages these data in the data base 5 to own the data base 5 in common by terminal units 21 to 2N in the work place.</p> |
