摘　　要：为评估改进浆喷桩工艺对矿山公路施工承载力及环境影响,通过现场实验和数值模拟,研究了桩长对地基加固效果的影响,并对比了改进方法与传统方法在环境污染控制方面的效果。结果显示,适当增加桩长能有效减少竖向变形,尤其在浅层地基中效果显著。在8 m深度处,桩基承载力提升最明显,达到25.52%。改进工艺在粉尘污染、土壤和地下水污染、噪声污染以及废弃物污染方面,污染率分别降低了23%、11%、18%和47%,表明改进工艺能有效减小对环境的影响。To assess the impact of improved jet grouting pile technology on the load-bearing capacity and environmental impact of mine road construction,the influence of pile length on the foundation reinforcement effects was studied through field experiments and numerical simulations.The results were compared with those of the traditional methods in terms of environmental pollution control.The results show that appropriately increasing the pile length can effectively reduce vertical deformation,especially in the shallow foundation.At a depth of 8 m,the pile foundation load-bearing capacity increased most significantly,by 25.52%.The improved technology reduced the levels of dust pollution,soil and groundwater pollution,noise pollution,and waste pollution by 23%,11%,18%,and 47%,respectively,indicating that the improved technology can effectively reduce environmental impact.
