四川省公路交通建设职工,在1959年的继续大跃进中,发扬了敢想敢干的共产主义风格,创造性地试制成功100米跨径的竹索公路桥,现将这座竹索公路桥的设计与施工技术情况,简单介绍于下: 一、设计一、结构体系的决定。竹索受力时延伸率很大,且与竹索的编结加工质量有关,如采用超静定的结构形式,完工后的实际应力支配可能与设计中分析的情况相差很远,因此考虑在静定体系中加以选择。一为网式吊
In the continued great leap forward in 1959, the workers and staff of highway construction in Sichuan Province carried forward the communist style of daring to think it over and creatively trial-produced a 100-meter-long bamboo cableway bridge. Now that this bamboo-bridge highway bridge Design and construction technology, briefly introduced in the next: First, the design of a structural system of decision. When bamboo is stressed, the elongation rate is very high, and it is related to the knitting quality of bamboo cords. For example, if the structure is statically indeterminate, the actual stress control after completion may be far from the analysis in the design. Therefore, Set the system to be selected.
