针以衡炎高速公路全风化、强风化、中风化和弱风化板岩为研究对象,通过崩解特性试验、软化试验、无侧限压缩试验、剪切渗透性试验,系统研究板岩受水影响的水理特性。研究表明:水理性能由强到弱的排序为:弱风化板岩,中风化板岩,强风化板岩,强风化板岩;板岩具备强烈崩解特性;崩解指数与风化程度直接相关,程度越高,崩解越强烈。板岩越干燥,崩解效应越明显,大旱后突降雨,会导致板岩的强烈崩解,很容易诱发滑坡。
The water characters of whole flowering, high content flowering, mid flowering and sheet stones were studied with a series of lab tests. The results show that the chain of water characters of sheet stones (from strong to little is little flowering, mid flowering and high content flowering and whole flowering; Sheet stone has strong collapse character, and collapse index has some connections with flowering content, the higher the flowering content, the stronger the collapse character. The drier the sheet stone, the easier the stone collapse, and the landslide will occur.
