广州地铁八、九号线岩溶分布规律及工程影响浅析

Guangzhou Metro 8,9-line Distribution of Karst and the Impact of the Project

广州多条地铁建设穿越灰岩地层,岩溶对建设及运营的安全、成本影响极大。本文从八号线北延段着手分析沿线岩溶发育特征,结合九号线建设经验,试图结合其工程特性,评价岩溶地质环境对地铁工程的影响,并提出相应的处理措施。

Some subways in Guangzhou under construction across limestone formations,karst have a great impact on safety,cost of construction and operation of the subways. This paper begin to analyzes the lines' karst features proceed from the north extension segment line 8,combined line 9 construction experience,trying to combine their engineering properties,assess Karst geological environment's effect on the subway project,and propose corresponding engineering measures.
