Abstract:

Against the backdrop of the integrated construction project for the Guangzhou Baiyun Station（Tangxi Station ） comprehensive transportation hub, a systematic investigation and analysis wereconducted on issues encountered during construction, including karst treatment, groundwater seepage atthe foundation level, and structural water leakage. This paper summarizes karst treatment technologiesfrom aspects including investigation plan design, treatment methods, and effectiveness. It also compilesemergency response protocols for sudden water inflow incidents, analyzes structural cracking and leakageissues under both visible and invisible water conditions, and develops comprehensive treatmentapproaches. The effectiveness of these techniques was validated through practical engineeringapplications.
