摘要

摘要: 为研究浆液在不规则断层内的扩散规律,基于自仿射分形插值曲面理论构建不规则断层,结合裂隙岩体注浆理论对断层形态、浆液黏度和注浆孔的布置对浆液扩散的影响进行了深入研究。研究结果表明：断层凹凸不平使得断层宽度呈随机分布,导致浆液呈非圆（柱）形扩散,不能依据浆液扩散半径公式来设计和布置注浆孔间距；在断层窄处,节点注浆压力等值线间距小,压力梯度大,反之亦然；浆液黏度越大,浆液所谓的惰性越强,扩散距离明显缩短,在断层注浆工程中,应结合浆液流变试验和浆液扩散数值分析成果,来优化浆液选型及配比。

Abstract: To study the infiltration law of grouts during grouting in irregular faults, based on the theory of self-affine fractal interpolation surface to build irregular faults and the theory of fractured rock mass grouting,the influences of fault form, grout viscosity and layout of grouting holes on the diffusion of grouts are thoroughly studied. The following results are obtained: (a) the random distribution of fault width caused by uneven surface of faults leads the grouts to noncircular diffusion, so the grouting holes cannot be arranged according to the formula for grout diffusion; (b) for the narrow faults, the grouting pressure contour of nodal interval is small, and the pressure gradient is large, and vice versa; and (c) the greater the grout viscosity is, the stronger the so called inertia of grouts is, therefore, the diffusion distance of grouts is obviously shortened. So engineers should combine the rheological tests on grouts with numerical analysis results to optimize the selection and proportion of grouts.
