当桥梁工程由于任务紧迫需要在雨季期间进行施工时,用预估洪水的方法,适时防患,以避免和减少洪水对桥梁施工现场的危害,是组织雨季施工的重要的技术措施之一。桥梁工程在雨季进行施工时,由于没有注意预估洪水,经常发生洪水突然危及施工现场,以致抢救不及而遭受损失。但也有由于进行了预估洪水工作收到良好效果的前例,如咸阳渭河桥曾在雨季进行打椿、基础及墩台工程,利用上游郿县水文站电话报洪水情况,基本上掌握了洪水到达桥位的时刻和洪水位的标高,在洪峰没有到达咸阳以前的8～10小时内,作好各项防洪准备,
When the bridge project needs to be constructed during the rainy season because of the urgent task, it is one of the important technical measures to organize the construction of the rainy season by predicting the flood and preventing it in time to avoid and reduce the harm of the flood to the bridge construction site. During the construction of the bridge during the rainy season, due to the lack of attention to the estimated floods, frequent occurrences of floods suddenly endangered the construction site, resulting in loss of rescue time. However, there are also some precedents that have yielded good results as a result of the estimated flood work. For example, Xianyang Weihe River Bridge used to hit silos, foundations and pier projects in the rainy season. By using the upper reaches of Shexian Hydrological Station to report floods by telephone, it basically mastered flood arrivals Bridge bit time and the elevation of the flood level, in the peak did not reach the Xianyang before 8 to 10 hours, make all the flood control preparations,
