合福铁路某区段钙质页岩边坡顺层滑坡,经过对顺层滑坡工点钙质页岩地貌、构造、岩性、风化、水文特征及施工影响等方面的综合分析,得出滑坡形成原因,并据此对其采用综合防治措施。通过施工后长期的变形监测及季节考验,该区段边坡稳定,处理效果良好。特殊地貌构造产出的钙质页岩,易产生岩层断裂及顺层滑动,施工时需分级刷坡支护,坡脚支挡结构应分段开挖施工。
閤福鐵路某區段鈣質頁巖邊坡順層滑坡,經過對順層滑坡工點鈣質頁巖地貌、構造、巖性、風化、水文特徵及施工影響等方麵的綜閤分析,得齣滑坡形成原因,併據此對其採用綜閤防治措施。通過施工後長期的變形鑑測及季節攷驗,該區段邊坡穩定,處理效果良好。特殊地貌構造產齣的鈣質頁巖,易產生巖層斷裂及順層滑動,施工時需分級刷坡支護,坡腳支擋結構應分段開挖施工。

In view of the landslide of one section of calcareous shale slope on HeFu Railway, a comprehensive analysis is conducted to root its causes in perspective of the landform, structural, lithologic, weathering, and hydrological conditions, and corresponding measures are taken. The long term observation of deformation shows that this section after construction is stabile and the treatment is effective. The calcareous shale in special geological area is likely to generate bedding slide and rock fracture, and the calcareous shale bedding slope should be graded with necessary support during construction, the slope retaining structure should be excavated in sections.
