The water resistance performance of the weathered and filled zone of the TOL as well as the feasibility of using the zone as an aquifuge were comprehensively studied using laboratory tests, in-situ tests, and spatial distribution features of the regional strata. The research results show that the weathered and filled zone has competent strength and reliable water resistance performance and can be used as a water barrier where the weathered and filled zone is ubiquitous with little influence of tectonic structures.
