| 摘 要： | 对于破碎范围较大且比较严重的巷道围岩进行注浆加固,其加固效果受注浆关键参数—注浆滞后时间、注浆压力、注浆量、注浆持续时间以及浆液扩散半径影响较大。在综合分析研究各个关键参数的基础上给出了其计算公式,为此类巷道围岩注浆加固关键参数提供了合理的选择。

| Abstract: | When the surrounding rock of a tunnel is relatively broken,concrete injecting is a efficient method to reinforce the surrounding rock,and the reinforcement effect is mainly controlled by following parameters: injecting delay time,injecting pressure,injecting capacity,injecting time and concrete spreading diameter.In this paper,the five parameters mentioned above is analyzed and some experiential formula were given out to supply a reasonable injecting parameters in tunnel surrounding reinforcement. |
