Abstract

Taking the danger removal and reinforcement project of Tunliu Reservoir in Guangxi as an example, aiming at the engineering geological problems existing in each dam and building during the operation of the reservoir, the permeability of the dam body, dam foundation and abutment rock and soil mass, the filling quality of the dam body, and the weathering state of the dam foundation and abutment rock mass are found out, which provides geological data and suggestions for the danger removal and reinforcement design. The geological investigation and evaluation of the foundation (surrounding rock) and material field of each reinforcement, reconstruction or new building are carried out. The key points of geological investigation of danger removal and reinforcement of large homogeneous earth dam reservoir are summarized, and the key technologies of geological investigation are put forward. It can provide reference for the geological survey work of other similar reservoirs.
