| Abstract: | The foundation of Dawancun super-large bridge of the new railway of Zhangjiakou to Jining sit in basalt stratum.The stratum height is uneven,and the strength difference of the same stratum is large because of different degree of weathering and impaction,which bring large risk for construction of bored pile.The author mainly introduces the key construction points of drilling hole of bored pile under basalt stratum condition. |
