摘要:
以重庆江习张家岩Ⅳ级泥岩段隧道为爆破研究对象,根据张家岩隧道实际工程的地质结构与地层岩性,基于X射线衍射试验和室内力学试验,获得泥岩的基本物理力学参数.从微差、孔间距、孔径、装药量四个方面综合分析其对爆破效果的影响,采用正交试验制定了泥岩隧道爆破模拟方案,并借助ANSYS/LSDYNA显示动力分析程序,对隧道的爆破参数进行优化,得到了泥岩隧道的爆破优化方案,通过对比分析,筛选出最优爆破方案.最后,将最优爆破方案与现场测试结果进行对比,结果表明模拟结果和测试结果基本吻合,且优化后的爆破效果要明显好于原爆破效果.研究成果可在类似隧道提出针对性爆破参数设计建议并推广应用.
Abstract:
Taking the Zhangjiayan IV mudstone section tunnel of Chongqing Jiangxi as the blasting object, according to the geological structure and lithology of the actual project of the Zhangjiayan tunnel, the basic physical and mechanical parameters of the mudstone were obtained based on X-ray diffraction test and laboratory mechanical test. From the four aspects of the differential, hole spacing, aperture, and charge amount, the impact of the blasting on the blasting effect was analyzed comprehensively. The simulation scheme of the mudstone tunnel blasting was formulated using orthogonal test, and the dynamic analysis program was displayed with ANSYS/LS-DYNA. The blasting parameters were optimized to obtain a blasting optimization program for a mudstone tunnel. Through comparative analysis, an optimal blasting scheme was selected. Finally, the optimal blasting scheme is compared with the field test results. The results show that the simulation results are basically consistent with the test results, and the optimized blasting effect is obviously better than the original blasting effect. The research results can be proposed in a similar tunnel to the design of targeted blasting parameters and promote their application.
