ABSTRACT
From ancient times until now, the advance of human civilization has been closely tied to the development of civil engineering: for the settlement of people, a house should be built; for food supply, irrigation facilities should be built; for clothing, apart from cotton and hemp cultivation, mulberry planting, and silkworm breeding, a textile manufacturing factory should be built; and especially, for the development of modern articial bers, large-scale construction of a factory for chemical ber synthesis is needed; for communication and goods transportation, railways, highways, harbors, and airports should be constructed. Obviously, civil engineering has a close relationship with human life and national economy.
