Abstract
In karst areas, the construction of dams and reservoirs is critically dependent on addressing leakage issues, which are pivotal to the success of such projects. The spatial complexity and dynamic evolution of karst development determine the intricacy of karst leakage problems.
This paper analyzes the leakage characteristics of the Lanxi Reservoir, beginning with an introduction to the engineering geological and hydrogeological conditions of the study area. By comprehensively studying groundwater dynamics and physicochemical characteristics, the forms and pathways of karst leakage are analyzed, leading to the conclusion that the main leakage channels in the study area are dissolution fissures and underground river conduits, primarily located at the contact zone between C3mp2 and C3mp1.
Through the analysis and assessment of typical karst reservoir leakage projects, this study provides valuable experience and references for similar engineering endeavors.

Abstract
In karst areas, the construction of dams and reservoirs has always been critically dependent on addressing leakage issues. The spatial complexity and dynamic evolution of karst development determine the intricacy of karst leakage problems.
This paper analyzes the leakage characteristics of the Lanxi Reservoir. It first introduces the engineering geological and hydrogeological conditions of the study area. By comprehensively studying groundwater dynamics and physicochemical characteristics, the forms and pathways of karst leakage are analyzed.
It is concluded that the main leakage channels in the study area are dissolution fissures and underground river conduits, with the primary leakage pathways located at the contact zone between C3mp2 and C3mp1. Through the analysis and evaluation of typical karst reservoir leakage cases, this study provides valuable experience and references for similar engineering projects.
