广西下福水利枢纽工程钢筋场塌方处理

Reinforcement yard collapse treatment for Xiafu Hydraulic Complex in Guangxi

广西下福水利枢纽工程,其大坝上游钢筋场在三通一平阶段发生大面积塌方,出现险情。分析表明,引起塌方的原因是原边坡地质条件较差,且填土量过高。通过对塌方部位进行局部开挖、打槽钢、浇筑砼底板及回填砂卵石等处理后,效果良好。

The reinforcement yard of Xiafu Hydraulic Complex in Guangxi was arranged upstream of main dam. Large area of collapse happened there during the period getting work site ready for construction. The results of analysis demonstrated that fairly poor geological conditions of the original side slope and excessive earth filling height are the major causes. The treatment measures adopted include local excavation at the collapsed position, inserting channel steel, grouting of concrete base slab, sand gravel backfill etc., rendering good effect.
