随着我国建筑事业的发展,将会愈来愈多地遇到膨胀土地区边坡的失稳问题。对于膨胀土或膨胀岩边坡,采用传统的稳定性分析方法,其结果与实际存在较大的差异。这是由于膨胀土或膨胀岩有其固有特性的原故。下面提出一种新的滑坡稳定性分析计算模式,来分析滑床为膨胀性泥岩的宝成线K105滑坡的稳定性。该工点概况及地质条件详见本刊总36期第48页。 With the development of China’s construction industry, there will be more and more problems with slope instability in expansive soil areas. For the expansive soil or the expansive rock slope, the traditional stability analysis method is adopted, and the results are quite different from the actual ones. This is due to the inherent characteristics of expansive or expansive rock. A new landslide stability analysis and calculation model is presented below to analyze the stability of the K105 landslide on the Baocheng line of swelling mudstone. The details of the site and its geological conditions can be found in the 36th issue of this publication on page 48.
