“…With the rapid development of global transportation and communication, there is an increasing demand for infrastructure projects such as railroads in many developing countries and regions (Ai et al, 2014;Hodgson, 2018;Pang et al, 2023). As a common large-scale accessory project during mountain railroad construction, tunnels can greatly improve railroad traffic efficiency (Xiao et al, 2019). They play important roles in improving route alignment, shortening track length, and increasing the operational efficiencies of railroads (Komu et al, 2020).…”

“…This can result in wasted water resources, local depletion of water resources, and water deficits for domestic, industrial, and agricultural use (Jin et al, 2012;Qingqing et al, 2014;Ding et al, 2021). Therefore, many scholars have attempted to predict how tunnel water surge will affect the groundwater environment using groundwater modeling and simulation techniques before tunnel excavation begins (Chiu and Chia, 2012;Xiao et al, 2019;Chen et al, 2021a). This can provide effective strategies for anticipating and reducing the impacts of tunnel water surge on water resources.…”

Tunnels play a significant role in mountain railroad routes and increase the efficiency of railroad traffic. However, water surge from tunnels can seriously impact the ecological environment during the construction period. This study selected a typical mountain railroad tunnel in southwest China and used the Remote Sensing Ecological Index (RSEI) to evaluate the changes in the ecological environment along the tunnel surge water path and relate the impacts to the main influencing factors throughout the whole tunnel construction cycle. The following conclusions were obtained: (1) The RSEI from 2005 to 2020 mostly ranged within 0.25-0.75. The most severe ecological disturbances occurred in areas directly affected by tunnel construction and along the water surge path; (2) in addition to affecting the surrounding ecological environment during the construction period, tunnel surge water continued to adversely affect the environment during the post-construction period; (3) in the post-construction period, the areas 300-450 m and 750-850 m from the tunnel exit had the largest changes in RSEI. This study provides scientific evidence to

This study provides scientific evidence to support environmental planning for mountain railroad tunnel construction, which is necessary to achieve both efficient tunnel construction and environmental protection.

“…Water inrush is one of the common geological disasters for the construction of traffic tunnels, and usually poses great negative impacts on the tunnel construction in terms to security, cost and time (Li et al 2015;Xiao et al 2019;Yau et al 2020;Zhang et al 2019). Due to the great potential hydraulic conductivity in karst aquifers, tunneling in karst terrains has a greater possibility to encounter disastrous water inrush accidents (Li et al 2013).…”

Tunnel excavation has significant disturbance on groundwater system and related geo-environment, especially in karst regions like southwestern China. The present research was conducted to quantitatively understand the negative impacts posed by tunnel construction on the karst groundwater system and reveal the behavior of karst groundwater system under the tunnel disturbance, with the aid of field survey, hydrogeological analysis, and numerical simulation. The results suggested that negative impacts such as loss of surface and underground water, ground collapse, and house deformation would be posed directly and indirectly to the karst groundwater system and its dependent geo-environment as the result of groundwater level drawdown by tunnel excavation. The degree and range of groundwater drainage impact were determined by the lithological and hydrogeological characteristics of strata. These negative impacts were dominantly distributed in the karst depressions valleys, and the direct ones occurred at first and followed by the indirect ones. Simulation results showed groundwater level drawdown would not occur synchronously in spatial, but always occurred around the tunnel axis at first and gradually expanded towards far away over time. The maximum disturbance on groundwater system can reach to approximately 25 m vertically and 3000 m horizontally for present modeling tunnel. With the aid of numeral simulation, three response stages were identified for the karst groundwater system behavior to the tunnel disturbance. The impacts of tunnel practice on groundwater and surface water bodies can be gradually eliminated since the second stage, but would continue if existing failure of tunnel waterproof until a new balance state achieved. The present research can improve the understanding of the impacts of tunnel excavation on karst groundwater system and dependent geo-environment, and provide reference to the protection of water resources and geo-environment in karst regions like Chongqing worldwide.
