膨胀土是自然界中一类危害严重的灾害性土,对膨胀土地区滑坡的防治提出了挑战。鉴于此,在详细研究膨胀土地质特性和工程性质的基础上,深入分析了广西上思地区某膨胀土滑坡的影响因素和成因机制,并开展了膨胀土边坡防治新型支挡结构的研究,工程实践表明该结构对膨胀土滑坡具有较好的防治效果。研究成果可为类似膨胀土地区滑坡防治提供一定的借鉴与参考。
Expansive soil is a kind of serious disastrous soil in nature, which poses a challenge to the prevention and treatment of the landslide in expansive soil area. In view of this, based on the detailed study of the geologic characteristics and engineering properties of expansive soils, the influencing factors and the formation mechanism of some expansive landslides in Shangsi, Guangxi are analyzed in depth. The research on the new type of retaining structures for expansive soils slopes is carried out. Engineering practice shows that the structure has good control effect on expansive soil landslide. The research results can provide some reference and reference for landslide control in expansive soils.
