We examine the association between board centrality and corporate environmental disclosure using hand-collected data from Chinese-listed firms in heavily polluting industries. We find that board centrality has a positive effect on corporate environmental disclosure. We also show that this positive effect emanates from the critical role of the board in monitoring and resource distribution, and its incentive to promote information transparency. Our results, which are robust to a set of robustness checks, have important implications for both regulators and investors. • We provide evidence that board centrality influences corporate environmental disclosure. • We find a positive association between board centrality and environmental disclosure using a sample of Chinese firms. • The effect is more pronounced for firms with CEO duality, and those with no directors' and officers' liability insurance. • Our results are robust to alternative estimation methods and proxies for board centrality.

• Shield tunnel lining damage induced by soil-water inrush is studied. • Numerical simulation matches with field results reasonably. • Strength reduction method have been applied for the consideration of soil loss. • Lessons learned from this incident have been presented. This paper reports a case study on shield tunnel lining damage induced by soil-water inrush occurred in Tianjin Metro Line 1, China through both field monitoring and numerical simulation. This incident was triggered by the non-watertight boring work of thru holes adjacent to the cross passage between the twin tunnels. Under high hydraulic gradient, the seepage-prone weak zone was formed and extended, then the outburst of soil-water slurry was occurred. Measures including plugging engineering cotton, injecting quick-setting cement and welding partition plate of steel segments, had been taken but in vain. The outburst of soil-water slurry induced soil movement around the cross passage, thus leading to the damage of tunnel lining and ground surface settlement. After sealing the water ingress holes, stabilization methods including surface grouting and inside tunnel back grouting were applied. The mechanisms of segment lining damage and the effectiveness of stabilization are investigated through both numerical simulation and field monitoring data analysis. Lessons learned from this incident have been discussed, thus providing reference for potential shield tunnelling under similar engineering conditions. [ABSTRACT FROM AUTHOR]
