岩溶充水隧道涌水量系数的探讨

INQUIRY ON COEFICIENT OF GUSHING WATER QUANTITY OF KARST WATER TUNNEL

我国实践中普遍认为采用均衡法：Ｑｃ＝η·Ｑｓ（Ｑｃ—预测隧道涌水量；Ｑｓ—降水渗入地下的渗入量；η—涌水系数）预测岩溶充水隧道涌水量较符合实际。然降水渗入地下的渗入量（Ｑｓ）有多少转换成隧道涌水量（Ｑｃ）？尚难解决，仍需完善。本文从实践中通过有关相关关系推演，提出了可行的和实用的η（涌水系数）的取值。

In China's practice, it is commonly accepted that it conforms to the practice toprognosticate the tunnel gushing water quantity in karst area with equilibrium method: Qc= η. Qs: (Qc-tunnel gushing water quantity prognosticated 1 Qs - seepsge quantity of precipitation seeped into the ground;η- coefficient of gushing water). But what still waits to besettled and perfected is that how much the seepage quantity (Qs) of the precipitation seepedin the ground is converted into the gushing water quantity (Qc). This paper makes an inference from the correlated relations in practice and puts forward a practicable and practical selection of coefficient of gushing water.
