摘要
广州北部地区燕山期花岗岩常发育有孤石,钻孔孤石发育率44%～75%,其发育程度受地形地貌、地质构造及地下水等因素影响,区内孤石分布与特征极其不均,文中就工程建设的适宜性与基础选择等进行评述,以期对该地区工程建设提供参考。
Solitary stone is exist in the area of north Guangzhou,the probability of water-eroded cave existing in one drill is 44% to 75%, the factors main affecting developing degree of water-eroded Cave incluce topography,geologic structure,groundwatero Considering the dis- tribution and character of the solitary stone is very misproportion therefore,the feasibility of engineering construction and the selection of base foundation are specially discussed in this paper,the result is hoped ;ome reference to the engineering construction in this area.
