采用多种方法对湖北襄樊引丹五干渠渠坡滑坡进行了整治和防护。结果表明掺砂改善膨胀土回填治理膨胀土滑坡和土工织物加筋治理膨胀土滑坡是成功的。本文介绍了这两种方法对膨胀土滑坡进行治理的设计、施工和监测结果。 A variety of methods were used to rectify and protect the Duanpo landslide of the Fifth Qujiang Canal in Xiangfan, Hubei Province. The results show that it is successful to use sand to improve expansive soil backfill to treat expansive soil landslide and geotextile reinforcement to treat expansive landslide. This paper presents the design, construction and monitoring results of these two methods for the treatment of expansive soil landslides.
