摘　　要：轨道交通工程作为线路工程,长距离跨越不同时代、不同岩性地层,不同特殊岩土或不良地质作用影响频繁,在工程建设期及运营期均存在一定的地质安全风险。岩土勘查作为设计、施工的基础,需针对不同地质情况科学采取不同勘查手段,查明工程地质、水文地质条件,满足工程建设需要,并对相关地质风险提出防范建议。文章针对广州地铁十四号线二期勘查过程中特殊地段采用的相应勘查手段进行说明,以期为类似工程提供借鉴。As line engineering,rail transit engineering has a long distance across different ages and different lithologic strata,and is frequently affected by different special rock and soil or unfavorable geological effects,so there are certain geological safety risks in the engineering construction period and operation period.As the basis for design and construction,geotechnical investigation needs to adopt different investigation methods according to different geological conditions,fi nd out the engineering geological and hydrogeological conditions,meet the needs of engineering construction,and put forward prevention suggestions for related geological risks.This paper explains the corresponding investigation methods used in the special section of the second phase investigation process of Guangzhou Metro Line 14,in order to provide reference for similar engineering.
