临时船闸及升船机工程，最大开挖深度150m，岩石开挖总量1455．81万m3，开挖边坡面积30多万m2，钻孔总进尺180万m。一期开挖边坡，全部采用预裂爆破，预裂深15～28m，总进尺40万m。升船机深槽开挖，改深孔预裂为9～28m梯段台阶预裂。无保护层一次性爆破时，采用垂直孔孔底设置柔性垫层的方法保护建基面。根据不同部位对爆破质点振速的要求，求出爆心距、不同边界条件下的允许单段药量，进而确定其他爆破参数，确保了保留岩体和新浇混凝土不致遭到震动破坏。
Temporary ship lock and ship lift engineering, the maximum excavation depth of 150m, the total rock excavation of 14,558,100 m3, excavation slope area of more than 300,000 m2, drilling a total footage of 1.8 million m. A excavation slope, all using pre-split blasting, pre-split depth of 15 ~ 28m, the total footage 400,000 m. Excavation of deep tank excavation, change the deep hole pre-split for the 9 ~ 28m step staircase pre-split. Unprotected disposable blasting, the use of vertical holes at the bottom of the hole to protect the construction of flexible cushion cushion. According to the requirements of blasting particle velocity in different parts, the allowable single-section charge under different boundary conditions can be obtained, and other blasting parameters can be determined to ensure that the retained rock mass and fresh concrete can not be damaged by vibration.
