摘要：AbstractThe corrosion of waste canisters in the deep geological disposal facilities (GDFs) for high-level radioactive waste (HLRW) can generate gas, which escapes from the engineered barrier system through the interfaces between the bentonite buffer blocks and the host rock and those between the bentonite blocks. In this study, a series of water infiltration and gas breakthrough experiments wer...

关键词：In situ loading of a pore network model for quantitative characterization and visualization gas seepage in coal rocks
摘要：AbstractThe flow characteristics of coalbed methane (CBM) are influenced by the coal rock fracture network, which serves as the primary gas transport channel. This has a significant effect on the permeability performance of coal reservoirs. In any case, the traditional techniques of coal rock fracture observation are unable to precisely define the flow of CBM. In this study, coal samples were s...

关键词：Triaxial compressive behavior of highwater material for deep underground spaces
摘要：AbstractAttributed to its superior water-to-solid ratio and quick setting time, the high-water material is widely adopted in underground spaces as a cost-effective and environmentally friendly backfill material. To elucidate the bleeding mechanism of high-water material under the high confining pressure, a total of 57 tubular specimens were prepared and tested, critical parameters of which incl...

关键词：Analysis of squeezinginduced failure in a water tunnel and measure rehabilitation A case study Tishreen Syria
摘要：AbstractSqueezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure. For this reason, it is highly imperative to analyze and identify a suitable methodology to estimate the squeezing potential and select a proper support system of rock mass. This study aims to reveal the causes of failure of Tishreen...
