摘要
对废弃窑洞的回填提出几种回填方法,通过比较、优选,选择专利发泡砂浆回填.运用FLAC3D软件进行回填数值模拟,并选择典型剖面记录此剖面在人工切坡、窑洞开挖、窑洞废弃依窑建房和废弃窑洞填充4个工况下的正应力、剪应力和剪切强度进行对比,同时计算各工况下的安全系数,进行对比分析.结果表明采用专利技术发泡砂浆对废弃窑洞进行填充,可有效避免发生坡体变形诱发滑坡.
The several backfill methods are proposed for the backfill of abandoned cave dwellings. By comparison and optimization the patented foaming mortar backfill is selected. Using the FLAC3 D software for the backfill numerical simulation, it chooses the typical profile record this profile in the artificial cut slope, the excavation of the cave which is abandoned in accordance with the kiln construction and abandoned cave populate the four conditions of normal stress, shear stress and shear strength were compared. At the same time, the safety factor of each working condition is calculated, and the comparison and analysis results show that the application of patented technology mortar to fill the abandoned cavities can effectively be avoided the slope deformation induced landslide.
