摘要
在青藏高原多年冻土区的铁路建设中,大量多年高含冰量冻土需要爆破开挖。国内外科研人员针对多年高含冰量冻土的爆破研究较少。对青藏高原沱沱河地区某一高含冰量冻土爆破漏斗的试验和爆破试验方法进行了研究。通过研究冻土特性、装药量和爆破深度之间的关系,得出了单位药包的最佳埋深、最大体积,进而推导出了最佳爆破参数。
Qinghai-Tibet railway is now being built, and much more frozen soil is needed to be blasted. However, only a few research works on the blasting of frozen soil had been performed. A number of explosion crater tests on ice-rich frozen soil were carried out along Qinghai-Tibet railway. The optimum depth and maximum volume are obtained, and the optimum blasting parameters are also achieved.
