裂隙岩体注浆模拟试验研究

通过在模拟的裂隙岩体中进行注浆试验，研究分析裂隙宽度d、注浆压力p、水灰比m的单因素和多因素对浆液扩散半径R、注浆后试件的抗压强度P和渗透系数K的影响规律和它们之间的相互关系。结果表明：R随着d、p、m的增加而增大，影响R最显著的因素是p，其次是d、m；P与d、p呈正相关性，与m呈负相关性，d对P有较大的影响，p次之，m则占有明显的优势；渗透系数K随着d、m的增大而增大，随着p的增大而减小，对K影响最大的是d，其次是p、m。利用计算机优化回归试验数据，得出了它们之间的关系式。

Experimental research on simulation of grouting in fractured rock mass

Through a grouting test in simulated fractured rock,the influence law and correlation of single-factor and multi-factor such as fracture width(d),grouting pressure(p),water cement ratio(m) upon grout diffusion radius(R),compressive strength(P) of grouted specimen,permeability coefficient(K) are analyzed.The results show that R increases as d,p and m increase,of which p is the most remarkable factor,followed by d and m;P is positively correlative with d and p,while negatively with m,and P is more affected by d than p,while m has the most significant effect;K increases with d and m,but decreases as p increases,and the most remarkable is d,followed by p and m.A relationship of them is established with the optimized data of computer regression test.
