摘要
分析了预裂爆破技术在层状复合岩体中作用机理,对梁万高速公路A合同段层状复合岩体路堑开挖中预裂爆破参数设计进行了探讨。由于层状复合岩体特殊性质,岩体内不同岩层对应不同的线装药密度。为了控制爆破危害,依据被保护对象的要求,除严格遵守安全规程外,还需采取一些特殊的安全措施。通过现场试验,获得了较好的爆破效果。
pre-splitting blasting technology mechanism in bedded composite rock was analyzed. Pre-splitting parameters design of bedded composite rock in A contract sect of Liang-wan freeway cutting blasting excavating was discussed. Considering especially property of bedded composite rock, different dynamite density was taken .In order to control blasting harm, except strictly abiding safety regulations, some special safety measures comply with protected object were taken The tests done in the field show that obtained results are useful.
