| 摘 要： | 闽东南沿海花岗岩广泛出露,其矿物成分差异明显,且受区域地质构造和湿热交替气候影响,花岗岩球状风化不良地质及其诱发的工程地质问题极为突出.粒径大小不一的风化球体受外界环境扰动,形成高空落石或坡面滚石,坚硬的风化球与残积土或全风化岩混杂的斜坡受降雨或开挖触发产生崩塌和滑坡,形成复杂的斜坡地质灾害.富含孤石的花岗岩地段开挖浅...

| Abstract: | Granite is widely distributed in the southeast area of Fujian Province.Granite spherical weathering and the relative engineering geological problems are very prominent because of differences of mineral compositions,regional geologic structure and warm-wet climate in this area.Spherically weathered rock blocks of various sizes fall from the top of slope or roll along slope surface.Collapse and landslide occur because of rainfall or excavation near slopes mixed with weathered spherical rock blocks and residua... |
