路基坡面防护空心砌块几何尺寸优化设计
Hollow block geometry optimization design in subgrade slope surface protection
摘要
Abstract
Hollow block frequently be used in subgrade slope protective engineering to prevent soil erosion resul-ted from rainfall on slope surface, and then guarantee the stability of slope surface. The rainwater seepage de-struction of loose soil erosion in hollow block are the main factors leading to block bottom cavity, local collapse of the protective structure. With the fill's critical slope angle as technical parameters, and with preventing soil ero-sion in the hollow block as control conditions, the function relationship between hollow block geometry size with the nature of the soil in hollow block the soil and slope gradient is established. The optimized geometries of the suggested values with the design safety reserve maintenance are put forward.关键词
