贵州南部某高速公路路堑边坡破坏机理和处治措施研究

Study on Failure Mechanism and Treatment Measures of Cut Slope of a Highway in South of Guizhou

对贵州省南部某高速公路路堑边坡病害进行现场调研,将沿线路堑边坡破坏形式分为7种,其中土质边坡分为类均质土边坡和松散破碎体边坡2种,岩质边坡归纳为顺倾、反倾、陡倾、斜交和上软下硬5种。通过调查沿线各种边坡岩土体形态及破坏形式,分析相应边坡的破坏机理,并针对每种边坡的破坏形式,提出相应的处治措施。

The cutling disease of the highway in the southern part of Guizhan province was investigated.We summarize the forms of failure along the slope is mainly divided into 7 types,in which the soil slope broken are homogeneous soil slope and the loose slope,rock slope can be divided into the dip slope,anti-inclined slope,steep slope,oblique slope and upper soft and lower hard.We investigated the forms and failure mode of various rock slopes along the line,analyzed and summed up the corresponding failure mechanism of slope.The corresponding protective measures are given for each slope.
