【摘要】 探讨大坝的长期变位规律,对监控大坝安全运行十分重要,也是个带有普遍性的问题。本文通过多种方案的分析计算,运用具体数据,指出了陈村拱坝的位移变化规律,并提出坝体位移安全运行参考指标。对于坝体目前出现的向上游前倾的变化,本文提出一些看法,供设计、施工方面今后工作中参考,同时提请运行部门引起足够的重视。更多还原

【Abstract】 To find out the regular pattern of long-term displacement of a dam is very important in dam safety surveillance. In this paper, the relevant data of Chencun Arch Dam are analyzed and calculated according to various schemes. By comparing the results from these different sChemes, the regular pattern of long-term displacement of the arch dam is found out and allowable displacement is proposed for reference. A discussion is also made on the inclination of the dam body toward upstream side.更多还原
