深坑酒店主体结构大面积遭遇坑壁围岩,需经爆破清理后方可进行施工。因坑深坡陡、作业困难,且不允许对保留岩体及坑顶已施工结构产生不利影响,因此对爆破施工安全质量要求高。经周密计算和验证,对围岩采用预裂爆破、浅孔爆破、中深孔爆破及膨胀剂破碎相结合的爆破施工方法,效果良好。
深坑酒店主體結構大麵積遭遇坑壁圍巖,需經爆破清理後方可進行施工。因坑深坡陡、作業睏難,且不允許對保留巖體及坑頂已施工結構產生不利影響,因此對爆破施工安全質量要求高。經週密計算和驗證,對圍巖採用預裂爆破、淺孔爆破、中深孔爆破及膨脹劑破碎相結閤的爆破施工方法,效果良好。

The main structure of Shanghai Shimao Chasm Hotel in large area suffered pit wall rock which needs to be cleaned before the construction carried out. Because of deep slope of the pit, difficulty operation, and does not allow for the retention of the rock mass and pit roof has a negative impact on the construction structure, high quality are required for blasting safety. Based on careful calculation and verification, blasting construction method combinated of pre?splitting blasting, shallow hole blasting, medium deep hole blasting and expansive agent was adopted, and good effect is obtained.
