摘要

摘要: 利用自溢井(孔) 做放水试验确定含水层水文地质参数, 是简便而经济的确定含水层水文地质参数的试验方法.涌水试验基本上属于定降深井流试验.在无限承压含水层中进行涌水试验, 使涌水孔(井) 降深s_w保持不变, 涌水量随时间的延续而减少, 除涌水孔(井) 本身以外, 含水层中任意点的水头H随时间的延续而降低.在单孔(井) 定降深井流试验利用涌水孔1/Q-lg t直线图解法计算水文地质参数的基础上, 建立一孔(主孔) 涌水多孔观测水位降低的直线图解法, 即s/Q-lg t直线图解法.

Abstract: The water gushing test in an artesian well, a simple and economical test method for confirmation of the hydrogeology parameter in the water containing layer, basically belongs to the test of constant drawdown yield. During the water gushing test in the infinite confined aquifer, the inrush of water and the random water head H in the confined aquifer decrease with the time, except the well itself, but the fall of well water s_w is kept unchangeable. The calculation of the hydrogeology parameter using the linear diagrammatized method l/Q-lg t in the constant drawdown yield test of single well, helps the authors to establish the linear diagrammatized method, s/Q-lg t method, in which one well is a main hole while the other wells can be used for watching the lowering of water.
