| 摘 要： | 本文在对某铁路(武广客运专线韶关-花都段)沿线花岗岩地段进行工程地质钻探的基础上,对该地段花岗岩球状风化的地下分布规律进行统计分析,揭示了在该地段地下隐覆的花岗岩风化球具有风化球埋深主要集中在0~40m之间、风化球竖向球径集中在0~5m之间、风化球表现形式主要为W3含W2的特点,并据此提出相应的工程建议。

| Abstract: | On the basis of geologic drilling in the granite area along the Shaoguan-Huadu section of the Wuhan-Guangzhou express railway,the occurrence of subsurface weathered-granite spheres is analyzed statistically in this article.The results show that(1) the weathered-granite spheres are mainly located at the depth of 0 to 40 m below the ground surface;(2) the vertical diameter of the weathered-granite spheres ranges from 0 to 5 m;(3) the appearance of the weatheredgranite spheres is mainly strong weathering-weak weathering-strong weathering. Thus,some relational engineering advice is also given in this paper. |
