| 摘 要： | 广州地区轨道交通沿线岩溶是在有利的地层条件、地质构造条件和水文地质条件下形成的。溶洞高度大多数小于3m,溶洞埋藏较浅,溶洞顶板较薄等。岩溶分布规律与发育程度主要受岩性、地质构造、地下水位变化等因素的控制。查明岩溶形成条件、分布规律和特征,对于隧道施工风险防范具有重要意义。

| Abstract: | The karst in Guangzhou was developed under favorable geologic conditions including strtigraphy,geological structure and hydrogeology.The height of the most caves are less than 3 m.The buried depth is shallow,and the thicknesss of the cave roof is thin.The distribution and degree of development is controlled by lithologic characters,geologic structure,the fluctuating underground water table and other factors.It is important to explore its forming conditions,distribution rule and character for avoiding tunnel... |
