摘要
简要介绍了FLAC3D程序基于多孔连续介质的渗流理论。通过考虑注浆浆液的粘度和渗透系数的时变性,以及多孔介质的流体流动方法,采用FLAC3D软件模拟分析了某超高层建筑钻孔灌注桩桩端后注浆的扩散范围,得到其在桩端以下为半椭球体。
This paper introduces the porous continuous media seepage theory based on the software FLAC3D. It considers the time-varying property of viscosity and permeability of grout. With the fluid flow method of por- ous media, FLAC3 D was used to simulate and analyze the diffusion area of post-grouted bored piles of a super- high-rise building. It was found that the shape of diffusion area is similar to a semi-ellipsoid.
