    南昆线八渡K343滑坡的工程地质条件及治理研究

    STUDY ON ENGINEERING-GEOLOGICAL CONDITIONS FOR LANDSLIDE AT BADU K343 SECTION NANKUN RAILWAY AND CONTROL ON IT

    • 摘要: 地质与物探综合研究表明 ,八渡滑坡是由于砂岩强风化层顶部富含高岭土等矿物 ,暴雨后饱水变为易流层 ,引起强风化和松散层重力失稳。滑动体厚度 2 0m左右 ,滑动面积近 3万m2 ,滑动体积约 6 0万m3 。在查清了地质条件的基础上 ,提出了抗滑与治水并重的治理方案.

       

      Abstract: An integrated geological and geophysical investigation suggests that the landslide at Badu K343 occurred because the top of strong weathering zone on sandstone is rich in kaolin and other minerals which became liguid layer by water saturation after torrential rain and caused the weathering zone and loose sediments to undergo gravity instability. The landslide body is about 20 m in thickness, 30 thousand m 2 in cover area, and 600 thousand m 3 in the slip volume. Based on the investigation of geological conditions, a proposal on building of piles and ditches for control on the landslide is suggested.
