云阳山隧道施工涌水环境影响与监控研究

Study on Monitoring and Environmental Effects of the Gushing Water from Yunyang Mountain Tunnel

根据新建衡茶吉铁路云阳山隧道的水文地质条件,通过预测隧道涌水量,分析预测隧道涌水、洞顶漏水对顶部泉眼、地下水、植被等生态环境以及居民生活用水产生的影响,表明隧道施工将会对隧道洞身上方泉眼产生影响,但是对山顶植被影响较轻。在此基础上,提出监控工作实施方案,从而可以为采用防治措施,提供科学、合理、准确的依据,减少隧道开挖对生态环境以及居民生活产生的影响。

According to the hydrogeology condition of Yunyang Mountain tunnel in the newly built Heng-Cha-Ji railway, by water gushing capacity prediction, the paper predicted the influences the tunnel gushing water and roof leakage have on spring mouth and plants on the top, groundwater and the residents. The results show that the construction will seriously affect the spring mouth but slightly influence the plants. Based on this, the paper proposed monitoring scheme, in order to provide scientific, reasonable and accurate evidence for taking prevention and treatment, consequently decreasing the influence on ecological environment and residents.
