| 摘 要： | 锚注加固是一种理想的改善软岩巷道的围岩承载性能的措施。在实验室对粉煤灰-水泥锚注加固注浆材料的流动性、析水性及抗压强度进行了试验研究，找出了注浆材料的适宜配比，即粉煤灰掺量在20 %以下，水灰比为0.65～0.70，并在新集三矿极软岩巷道修复加固中进行了应用。

| Abstract: | Bolt and grouting reinforcement is an ideal measure for improving performance of bearing capacity of soft surrounding rock around tunnel in soft rock. Based on the test and research for fluidity,performance of separating water and compressive strength of fly ash and cement grouting material in laboratory,grouting material with a proper mixture rate is found (fly ash colume fraction is less thom 20 %,water to cement ratio is from 0.65 to 0.70) An engineering practical example is given that fly ash and cement grouting has been used in very soft rock roadway at the Xinji NO.3 mine in Huainan. |
