山区中小河流河岸工程地质分段与评价——以重庆市大宁河巫溪县城河岸整治工程为例

Geological segmentation and evaluation of small and medium-sized riverbank projects in mountainous areas:riverbank regulation project of Da′ning River in Chongqing

为给山区中小河流河岸整治工程设计提供依据,需对河岸进行工程地质分段和评价。以重庆市大宁河巫溪县城河岸整治工程为例,综合考虑山区中小河流河岸地形地貌、岸坡稳定性,整治工程地基承载力值、地基沉降变形量、地基抗冲刷能力等地质因素,进行了工程地质分段与评价。可为整治工程设计提供依据,亦可为其他类似工程提供参考。

To provide the design basis of small and medium - sized riverbanks regulation in mountainous areas, the segmentation and evaluation of engineering geology is conducted with the case of riverbank regulation on Daning River, Wuxi County of Chongqing, with the consideration of geological factors such as topography, slope stability, bearing capacity of foundation, settlement amount, and anti - erosion ability. The results provide the basis for the design of the regulation works and also a reference for other similar projects.
