Key technology for the construction of foundation pit support under unbalanced force condition
After analyzing the deformation and force situation of pit support for the main bridge P3# pier of Yellow River Bridge in the reconstruction and expansion project of Beijing-Taipei expressway from Qihe to Jinan,the construction method of"locking steel pipe piles as pit support+drilled piles for reinforcement and protection"is adopted through the selection of schemes and the key construction techniques are optimized,which can solve the construction problems of steel pipe piles under the condition of unbalanced force better.The key construction techniques were optimized,which better solved the construction problems of steel pipe piles under unbalanced stress conditions.
