摘要
在贵州东南部与广西、湖南交界地带分布着大面积古老的浅变质岩地层,其独特的工程特性给在建的厦蓉高速公路带来严重的地质灾害,极大地增加了工程成本和施工难度。文章阐述了黔东南一带浅变质岩地层工程特性及变形破坏机制,并对公路建设过程中的边坡防护治理措施进行初步探讨。
In the southeast of Guizhou, which borders Guangxi and Hunan, are large areas of ancient epimetamorphic rock strata, whose unique construction characteristics has caused great geological disasters to the construction of Xiarong Expressway and caused higher projects cost and difficulties. The paper explains the unique construction characteristics and deformation mechanism in this region and probes into the preventive measures of slopes.
