切槽爆破研究的历史及现状

Development of Investigation on the V-notched Rock Blasting

简要回顾了切槽爆破的起源及在工程中的应用 ,介绍了文献中几种主要的切槽爆破的机理研究、切槽尖端应力强度因子的研究现状以及影响切槽爆破的主要切槽参数并作了简单评述。最后 ,提出了螺旋切槽松动爆破的方法及优点。

A brief review on the origin of V-notched blasting and its application in engineering is given. A study on the fracturing mechanism and stress intensity factor at the tip of V-notch and parameter of the V-notched rock blasting is introduced based on reference given in this paper. It represents an idea of spiral V-notched blasting at last.
