摘　　要：研发一种智能灌浆设备进行素填土注浆加固试验,研究了注浆深度对注浆施工参数的影响;分析了不同注浆方法的适用性和功效,探索了浆液的实际扩散情况。研究发现:注浆压力和注浆深度、注浆方法、注浆次序密切相关,可根据项目前期注浆试验结果确定注浆参数;浆液基本沿着土层内某些薄弱通道扩散,形成了多道浆脉;利用智能灌浆设备进行注浆加固试验,可快速地确定合适的注浆参数,为后续施工提供技术指导。An intelligent grouting equipment was developed,and grouting reinforcement tests were conducted on plain fill soil using the grouting equipment.The influence of grouting depth on grouting construction parameters was studied.The applicability and effectiveness of different grouting methods were analyzed,and the actual diffusion of slurry was explored.The results showed that the grouting pressure is closely related to the grouting depth,grouting method,and grouting sequence,and grouting parameters can be determined based on the results of pre-project grouting tests.The slurry diffuses along some weak channels within the soil layer,forming multiple slurry veins.Using intelligent grouting equipment for grouting reinforcement testing can quickly determine suitable grouting parameters and provide technical guidance for subsequent construction.
