一、前言广西属半山丘陵地区,灌溉渠系工程中,跨越建筑物甚多,渡槽以其结构受力明确、易于就地取材、施工和维护方便、外形壮观等特点,广为设计者所采用。据不完全统计,全区共有流量0.5米~3/秒以上的各类渡槽约千座。近年来,由于施工、设计、洪水、风暴、维护等原因,发生崩垮失事多起,造成经济损失,以致人身伤亡,教训沉痛。现将收集到的渡槽失事资料试作初步分析、探讨,藉以总结原因,吸取教训,提高技术
I. Preface Guangxi is a hilly area. In the project of irrigation canal system, there are many buildings across. The aqueduct is characterized by its stress-bearing structure, easy access to materials on site, convenient construction and maintenance, and spectacular appearance. It is widely used by designers. According to incomplete statistics, there are a total of about 1,000 aquatics of all kinds in the region with a flow rate of 0.5m ~ 3 / s or above. In recent years, due to construction, design, floods, storms, maintenance and other reasons, there have been many collapsing and causing economic losses, resulting in personal injuries and injuries. The aqueduct data collected now will be tentatively analyzed for preliminary analysis and discussion, so as to summarize the reasons, learn lessons and improve technology
