Abstract: Large amounts of water leakage and water inflow in tunnel will cause the drop of water level of the sur? rounding strata and induce a large area of strata subsidence, threatening the safety of constructions (structures) and pipelines in the surrounding area. Considering the influence of atmospheric precipitation recharge, a calculation method for drawdown in surrounding strata induced by tunnel water leakage is established based on areal well theory, and practical application and analysis are conducted. The results show: (1) the drawdown curve of surrounding strata induced by tunnel water leakage is in a shape of symmetrical "subsidence trough", the closer to the tunnel center the more significant the drawdown; (2) the drawdown develops in a trend of log function with continuous water leakage; (3) for the studied project, water blocking measures should be taken in light of the drawdown more than 3 m in a scope of 50 m nearby after continuous water leakage of 30 d.
