摘要
官地水电站地下厂房开挖施工时,严格控制爆破对边墙的振动影响,对设计进行优化,选择合理的爆破参数,爆破后及时进行支护,并应充分利用岩石弹性抗力。使地下厂房开挖的各项控制指标均在设计图纸、施工规范和合同技术条款要求范围内。
During the construction of underground powerhouse of Guandi hydropower station, the influence of blast on side wall is controlled strictly, the design is optimized, the reasonable blast parameters are choosed, the support is carried out timely and the elastic resistance of the rock are applided completely. The design control indexes are meet the requirements of the design drawing, the construction codes and the technical clauses.
