... Abstract The existence of karst caves brings great potential safety hazard to tunnel construction. When building a tunnel through underwater karst area, engineers will face greater challenges. This paper introduces the treatment technology of submarine karst caves, based on a large diameter...

... challenges to pipeline operation and tunnel construction. In this study, the numerical finite element method is used to analyse the engineering case of the shallow buried large section tunnel under the raw water pipe. Using reasonable tunnel excavation construction method, this paper analyses the influence...
