摘要: 为了研究注浆堵水帷幕的稳定性,利用MTS815.02电液伺服岩石力学试验系统对注浆帷幕体的渗透特性进行了试验,获得了注浆帷幕体受压破坏全过程的渗透特性。结果表明,随着压力增加,渗透系数逐渐增大,在应变达到某临界值后,渗透系数开始急剧增大,此时裂隙产生。另外,裂隙和注浆结石对渗透系数有明显的影响。

Abstract: To study the stability of grouting waterproof wall system, a test was made on the permeability of grouting wall by the MTS815.02 electro-hydraulic servo controlled rock mechanics testing system, and the permeability characteristics of grouting wall system in the whole process of compression fracture were identified.The result shows that the permeability coefficient will increase gradually with the pressure increase and drastically after the strain gets to a critical value, when the fissure will occur.Moreover, the fissures and grouting concretion have an evident effect on the permeability coefficient.
