摘要
本文从水动力和水化学两方面讨论了大屯孔庄矿副井井筒破裂与第四系底部含水层水文地质条件的关系，详细分析了底部含水层水文地质条件变化可能对底部含水层及其周围岩土体以及井筒受力状态和强度特征产生的影响。首次指出了底部含水层水动力变化在井筒外部受力环境分析中的重要性和水化学作用对井壁混凝土强度的损害性。
The relation between rupture of auxiliary shaft and hydrogeological conditions of bottom aquifer in Quaternary system is discussed from hydrodynamic and hydrochemical conditions in Kongzhuang colliery of Datun in the paper. The influences of the change of hydrogeological conditions on forcing state and strength characteristic of auxiliary shaft,bottom aquifer, and its surrounding rock-soil mass are analyzed in detail. An importance of hydrodynamic change in analysis of outer stress environment for the shaft and dormage from hydrochemical corrosion which has effect on strength of shaft lining concrete are first put forward.
