浅谈地震液化带地段桥梁深基坑开挖施工技术

On bridge deep foundation ditch excavation construction technique in the section of earthquake liquefied

详细分析了地震液化带软土地区桥梁深基坑开挖的施工问题,提出了真空轻型井点降水、钢管桩围堰和两者相结合的方案来解决施工过程中可能出现的喷砂冒水和滑坡等灾害,试验结果表明,用该方法进行深基坑开挖支护是十分有效的。

It specifically analyses the construction problems of bridge deep foundation ditch excavation in the section of earthquake liquefied soft soil area, puts forward the programs of vacuum light well precipitation, steel tube pile fender and the composition of them to solve the damages of sand-blast boil and landslide that easily happened in the construction. And the experiment effect indicates that it is effective of using this method to get the deep foundation ditch excavation and supporting.
