| 摘 要： | 冻土爆破开挖是青藏铁路建设中的一大难题。通过现场球状药包和柱状药包漏斗爆破试验 ,初步确定冻土爆破的炸药单耗 ,在此基础上 ,利用三次深孔路堑开挖爆破试验 ,确定了高含冰量冻土开挖的最佳爆破参数。

| Abstract: | The blasting excavation of permafrost is a difficult problem in the construction of Qinghai-to-Tibet railway.The powder factor for the blasting excavation of permafrost was preliminarily determined through the site crater tests using spherical or column charges.On the basis of above tests,the optimal blasting parameters for excavation of the permafrost with high ice content were determined by three longhole blasting tests for cut excavation. |
