梅大高速公路路基边坡失稳条件与滑坡机理初探OACSTPCD
Study on the instability condition and landslide mechanism of subgrade slope in Mei-Da Expressway
文章对广东梅大(梅州—大埔)高速公路路基边坡失稳和滑坡的成因机制进行了初步研究和分析,基于香港路基边坡失稳滑坡调查研究资料、成果和现场勘察获得了失稳路基边坡附近完全风化花岗岩土的颗粒分布和液限塑限含水率,定量计算、分析了该段路基边坡稳定性.通过Google地形图分析了失稳路基边坡附近的几个可能汇水区域和汇水量,对该路基边坡失稳与滑流的成因机制进行了分析.研究认为山坡公路建设需要开挖削坡和填土,可完全改变自然山坡汇水流域;公路可成为瞬态河流,将大量…查看全部>>
This paper presents a preliminary investigation of the instability and landslide of a road subgrade slope that occurred on May 1,2024 along Mei-Da Expressway.The investigation method is on the basis of past investigation results and findings about instability and landslide of road subgrade slopes in Hong Kong.The Mei-Da Expressway subgrade was constructed by cutting and filling on mountainous slopes.The landslide occurred at a fill slope along a gully.The fi…查看全部>>
