七律·长征

毛泽东 一九三五年十月


红军不怕远征难，
万水千山只等闲。
五岭逶迤腾细浪，
乌蒙磅礴走泥丸。
金沙水拍云崖暖，
大渡桥横铁索寒。
更喜岷山千里雪，
三军过后尽开颜。

Rope bridges acted as suspension bridges over canyons and gorges to provide access for the Inca Empire. Bridges were available to use since the Inca people had yet to discover the wheel. These bridges were an intricate part on the Inca road system and are an excellent example of Inca innovation in engineering. They were frequently used by Chasqui runners delivering messages throughout the Inca Empire. This article concerns modern suspended deck suspension bridges, commonly called suspension bridges. ...

Among the many roads and trails constructed in South America, the Inca road systems in Peru are most extensive yet constructed on the South American continent. ... Representation of a Chasqui The Chasquis were agile and highly trained runners who delivered messages and royal delicacies throughout the Inca Empire, principally serving the Sapa Inca. ...

The construction of these bridges amounted to a pair of stone anchors on each side of the canyon with massive cables of woven ichu grass linking these two pylons together. Adding to this construction, two additional cables acted as guardrails. The cables which supported the foot-path were reinforced with plaited branches. This multi-structure system made these bridges strong enough to even carry the Spaniards while riding horses after they arrived. However, these massive bridges were so heavy that they tended to sag in the middle, and this caused them to sway in high winds.

The suspension bridge is one of the earliest types, but it has not been developed or adopted as rapidly as other forms, owing chiefly to its lack of rigidity and the absence of correct theory for proportioning stiffening trusses. It was used in remote ages in China, Japan, India, Tibet, and by the Dyaks of Borneo, the Aztecs of Mexico, and the natives of Peru and other parts of South America. In all early forms the platform was supported directly on the cables, which consisted of twisted vines or straps of hide drawn tightly to remove floor sag, the cable ends being fastened to trees or other permanent objects on shore. Light bridges of this kind, requiring no piers, were economical, and are still common in Peru and in parts of China, India and Ireland. A more primitive bridge consisted of a single rope with a basket suspended from it, which was drawn back and forth by a smaller rope or cord. Single tight ropes were also used with smaller ones at higher levels, to form side support for the traveler. Definite information relating to the early history of bridges in China is lacking, but enough is known to prove that supensions were used in that country in very remote times. The first one of which the date is given was built A.D. 65 by order of Emperor Ming, in the province of Yunnan, and as described by Kirchen, was 330 feet long, with a plank floor resting on chains. A similar one at Tchin-Chien was 140 feet long, and another over the river Pei, several hundred feet in length. One in China with the floor resting on the iron suspension chains, resembling the rope bridges of South America, dates back to remote times, and later records show that all in that country before the sixteenth century had floors supported in this way. Foot bridges of this kind crossing ravines and rivers, permitted the Buddhist to reach his house or temple on the other side.
