关于成都膨胀土地区边坡稳定性的探讨

成都市三环路建设中 ,膨胀土边坡稳定性研究是大家关心的重要课题。膨胀土边坡土体中的吸力变化直接影响到其稳定性 ,参照“人工神经网络技术”中的吸力经验公式 ,以三环路东一B标段的路堤边坡为例 ,采用“条分法”进行预测分析 ,并有针对性地进行防护处理取得了较好的效果。

Probing into Side Slope Stability in Chengdu's Bentonite District

During the construction of Sanhuan Road in Chengdu City, the stability of bentonite side slope is an important problem for study. The change in attraction in the soil body of bentonite side slope will directly influence its stability, thus, referring to the empirical formula stated in "Artificial Nervous Network Technology" and taking the embankment side slope of B marked segment in Sanhuan Road East as an example, the forecast and analysis have been made by using "Stripe Method", and the protective treatment has been carried out with definite aim, so, good results have been gained.
