景观区膨胀土边坡失稳机理分析及其治理方法研究

Study on Failure Mechanism and Treatment Technology of Expansive Soil Slope in Landscape Area

选择膨胀土滑坡的治理方法时常常忽视其失稳机理的分析。文章根据镇江南徐大道黄山景观区膨胀土滑坡治理方法的分析研究及其工程实践,论证了景观区膨胀土边破失稳的机理与治理方法的相互对应,并为此类滑坡治理提供了成功的范例和经验。文章提出了导水、排水和抗滑桩支挡是此类膨胀土滑坡治理的关键方法,可以起到保护景观、恢复景观的效果。还提出了对此类膨胀土滑坡治理进一步分析研究的内容。

It has not been broadly accepted that there is certain relationship between slope failure mechanism of expansive soil and its treatment method. The correlation will be discussed in this paper and some examples or experiences for such landslide treatment will be provided based on the analysis and practice of the landslide treatment of expansive soil in landscape area of Zhenjiang Huangshan hill nearby Nanxu Avenue. It is advanced in the paper that the key of the methods for such treatment is water transmitting,draining and as well as slope bracing by anti - slide pile, for these methods are helpful to keeping and recovering the original landscape. The further research for such slope treatment is also put out in this paper.
