| 摘 要： | 为了更客观、准确地描述爆破对地下水发育地段裂隙岩体的破坏,在前人研究成果的基础上,讨论了在有节理裂隙等缺陷的岩体条件下,水不耦合装药爆破在岩体中产生的应力场,并通过理论推导得出了冲击波引起的岩体的粉碎区和应力波引起的初始裂隙区半径,用Mathematica软件作图得出了水不耦合装药爆破时最佳不耦合系数。

| Abstract: | In order to more objectively and accurately describe the destroy of the fissure-rock of underground water field under the blasting,on the base of some research productions some scholars did,this paper discusses the stress field in the joint fissure-rock under the water-uncoupling blasting load.Then the pulverizing and crack area radius equations by theoretical derivation were obtained.And the best uncoupling coefficient through plotting was got with Mathematica software. |

| Keywords: | Damage of rock Tension fracture,the best uncoupling coefficient |
