某一路堑开挖爆破周围环境复杂,为了降低爆破振动影响,采用了:减小孔网参数和单孔药量、孔内分层装药并延时起爆、孔内延时与孔外延时结合、孔底装填吸能材料和布置减振空孔等措施.经工程实践及爆振实测,采用的减振措施效果明显.
某一路塹開挖爆破週圍環境複雜,為瞭降低爆破振動影響,採用瞭:減小孔網參數和單孔藥量、孔內分層裝藥併延時起爆、孔內延時與孔外延時結閤、孔底裝填吸能材料和佈置減振空孔等措施.經工程實踐及爆振實測,採用的減振措施效果明顯.

The surroundings of a cutting blasting of roadbed is complex.In order to reducing the blasting vibtation effect,some ineasures,reducing the spacing of holes,decking charge and delay initiation in and out holes and with other measures of endergonic materials in holes bottom and clearence holes,were adopted.Through the practice and the vibration monitoring,the effect of reducing is evident.
