| 摘 要： | 在阐述多边界石方爆破理论的基础上,结合路堑高边坡岩体的工程特点,进行深孔控制爆破应用研究。由于路堑高边坡岩体爆破药量计算充分考虑地形、地质条件的影响,炸药爆炸效果得到有效控制。路堑开挖岩体在炸药爆炸能量和介质中潜在位能的共同作用下得到充分破碎;爆破未见飞石,破碎岩体全部坍塌在路基范围以内;同时,临近设计边坡采用缓冲爆破技术,爆后形成了稳定的路堑边坡。

| Abstract: | Based on expatiating the rock blasting theory under multilateral boundaryt,he thesis combines a project of a high and steep road cutting blasting and proceeds application study of deep hole control blasting.Because the calculating of charge quantity of a high and steep road cutting blasting considers the various landform and geological conditions,the blasting result is availably controlled.Under the combined effect of explosion energy provided by explosive and the latent positional energy in medium,the rock masse of road cutting is adequately broken up.The flying rock does not be seen and the fragmentation rock collapses to fall in the roadbed scope.At the same time,the cushion blasting technique is adopted nearby the road slope and a complete road cut slope is shaped. |
