运营期隧道地下水位变化情况估算
Calculation of underground water level for tunnel in operation period
摘要
Abstract
The method of "Blocking ground water and limiting discharge" is widely applied to deal with the groundwater of the tunnel with high groundwater table. However, it is inevitable to have the influence on the drawdown of the groundwater table when drains perpetually, if the level exceeds a certain limit. It will cause the deterioration of ecological environment. The operational period of a tunnel is usually so long that it is essential to real-time control the groundwater table. The calculation method of water inflow of surrounding rock and the lining of the tunnel was determined based on the contrastive analysis, groundwater dynamics method and Darcy's law, and then according to the seepage continuity, the back analysis method of groundwater table was obtained. Under the conditions of the tunnel flow rate, the permeability coefficient of surrounding rock and lining were known, the groundwater table can be obtained. It was proved to be effective by case study and the comparison of real project. This method can provide a reference to the groundwater table of the tunnel for operational phase as well as the basis of groundwater balance protection.关键词
