摘要： 通过从天柱山地区类土质边坡中取回的多组花岗岩风化后所形成的样品进行颗粒分析试验对比,结果表明样品颗粒不均匀系数明显偏大。由于级配较好,颗粒直径大小差异较大,在降雨情况下,坡面受冲刷作用严重,极易〖JP〗发生破坏。研究此类边坡浅表层风化物的情况,对天柱山地区风化花岗岩类土质边坡的防护提出生态防护建议。

Abstract: The granitic soil samples were collected from the saprolite soil slopes of Tianzhushan area and their grain size distributions were laboratory tested. The results indicate that the ununiform coefficients were obviously high. The samples were wellgraded and the sizes in the granular soil samples varied significantly. Under heavy precipitation condition, the saprolite soil slopes were easily damaged by the erosion. It is therefore, the slope protection becomes very important and the biological slope stability remediation measures are also proposed.
